Top 5 Motor Stator Cutter Suppliers in Japan [2025]

Founded in 1998 in Yokohama, Nippon Recycling Tech Co., Ltd. (NRT) has grown from a small engineering workshop to a global name in recycling machinery. What began as a focus on basic metal processing equipment evolved, in the early 2000s, into a specialization in motor recycling—an area where the company saw untapped potential for innovation. Today, NRT's motor stator cutter equipment is trusted by recycling plants across Asia, Europe, and North America, and it's easy to see why.

Their flagship model, the MSC-500 Motor Stator Cutter, is a testament to NRT's "precision meets practicality" philosophy. Designed to handle stators of all sizes—from small appliance motors to large industrial units—the MSC-500 uses a hydraulic cutting mechanism that delivers clean, burr-free cuts, minimizing metal loss and ensuring the copper windings remain intact for easy extraction. What truly sets it apart, though, is its integration with NRT's broader motor recycling machines equipment. Pair the MSC-500 with their shredder and pre-chopper equipment, and you get a turnkey system: motors are first stripped of casings by the pre-chopper, the stator is extracted, and the MSC-500 precisely cuts the stator laminations, allowing for quick separation of copper coils from iron cores.

NRT doesn't just sell equipment; they build partnerships. "We spend months on-site with clients before installation," says Yuki Tanaka, NRT's sales director. "A recycling plant in Osaka, for example, needed to process 500 motors daily. We customized the MSC-500's feeding mechanism to work with their existing conveyor system and added an automated sorting feature—now they're hitting 600 motors a day with fewer operators." This customer-centric approach, combined with a 24/7 global support hotline, has made NRT a favorite among large-scale recyclers.

Beyond motor stator cutters, NRT's lineup includes single shaft shredder equipment for general waste and auxiliary equipment like dust collectors, ensuring their systems are as eco-friendly as they are efficient. For businesses prioritizing scalability and reliability, Nippon Recycling Tech is a clear front-runner.

If NRT is known for scalability, Tokyo Precision Machinery (TPM) has made its name in precision—no surprise, given its roots in Tokyo's historic engineering district. Established in 1975, TPM initially focused on aerospace components before pivoting to recycling equipment in the 1990s, bringing with it decades of experience in crafting machines that operate with micrometer-level accuracy.

Their motor stator cutter equipment, the StatorPro X7, is a masterpiece of Japanese engineering. Unlike many cutters that rely on brute force, the StatorPro X7 uses a laser-guided alignment system to position the stator before cutting, ensuring each slice is exactly 0.5mm from the winding edge—enough to free the copper without damaging the valuable metal. "We tested 200 stator designs before finalizing the X7's blade geometry," explains Dr. Mei Wong, TPM's lead engineer. "The result? A 99.8% copper recovery rate, which for a plant processing 10 tons of motors monthly, translates to thousands of dollars in extra revenue."

TPM also understands that not all recyclers need a top-of-the-line model. For smaller operations, they offer the StatorPro Mini, a compact version that's lighter on the budget but still packs TPM's signature precision. Both models integrate smoothly with TPM's motor recycling machines equipment, including their 2 shaft shredder equipment for post-cutting material processing. What clients love most, though, is the durability. "A client in Germany has been using their StatorPro X7 for 12 years," Wong adds. "We replaced the blades once, but the frame and hydraulics? They're as solid as day one."

TPM's commitment to innovation is unwavering. In 2024, they launched a smart upgrade for the X7: IoT connectivity that lets operators monitor cutting speed, blade wear, and throughput in real time via a mobile app. Alerts for maintenance? Sent directly to your phone. It's this blend of old-world craftsmanship and new-world tech that keeps TPM at the forefront.

Osaka Eco-Engineering (OEE) is proof that sustainability and profitability can go hand in hand. Founded in 2005 by a team of environmental scientists and mechanical engineers, OEE set out to build recycling equipment that doesn't just process waste but actively reduces a plant's carbon footprint. Their motor stator cutter equipment, the Eco-Cut M3, is a shining example of this mission.

At first glance, the Eco-Cut M3 looks similar to other cutters, but under the hood, it's a green machine. Its hydraulic system uses biodegradable oil, and the motor is 30% more energy-efficient than industry standards, cutting electricity costs by an estimated $2,000 annually for a mid-sized plant. "We didn't stop there," says OEE's sustainability director, Akira Sato. "The cutter's frame is made from 80% recycled steel, and even the packaging for delivery is plastic-free—we use bamboo pallets and paper-based padding."

But eco-friendly doesn't mean underpowered. The Eco-Cut M3 can handle stators up to 500mm in diameter, with a cutting cycle time of just 15 seconds per unit. It also features a unique "dustless cutting" design: a built-in vacuum system captures metal shavings, which are then collected and recycled, eliminating waste and keeping the workspace clean. For recyclers focused on meeting strict environmental regulations—like the EU's REACH or California's Prop 65—this attention to detail is a game-changer.

OEE's product line extends beyond motor stator cutters to include a full suite of motor recycling machines equipment, such as the Eco-Shred 2000 (a low-noise shredder) and the MetalSort Pro (a magnetic separator for post-cutting material sorting). What really endears OEE to clients, though, is their "Green Partnership Program." When you buy an Eco-Cut M3, OEE provides a free energy audit of your recycling line, suggesting tweaks to maximize efficiency—like adjusting conveyor speeds or optimizing shredder settings—to further reduce your carbon footprint. "A client in Seattle saved 18% on their monthly energy bill after our audit," Sato notes proudly.

For businesses that want to do good while doing well, Osaka Eco-Engineering is more than a supplier—it's a sustainability ally.

Kyoto is known for blending tradition with innovation, and Kyoto Industrial Solutions (KIS) embodies this spirit perfectly. Founded in 1982 as a family-owned machine shop, KIS has stayed true to its roots of craftsmanship while embracing modern technology—making it a go-to for recyclers who value both reliability and cutting-edge features in their motor stator cutter equipment.

KIS's star product, the KIS-StatCut 3000, is a favorite among small to medium-sized recyclers. It's compact (just 2.5m x 1.8m), making it ideal for plants with limited floor space, yet it doesn't skimp on performance. The cutter uses a dual-blade system—one for rough cutting the stator from the motor housing, and another for precision slicing of the laminations—eliminating the need for multiple machines. "We designed it for businesses that are just starting their recycling journey," says KIS's owner, Takeshi Mori. "A lot of new recyclers can't afford a full production line, so the StatCut 3000 lets them start small, processing 100-200 stators a day, and then scale up as they grow."

What makes the StatCut 3000 stand out is its simplicity. The control panel has just three buttons: Start, Stop, and Adjust. "We've had clients tell us their 65-year-old plant manager learned to operate it in 10 minutes," Mori laughs. "No complicated menus, no technical jargon—just straightforward functionality." That said, KIS hasn't ignored tech: the latest model includes a USB port for exporting production data (like daily throughput and blade usage), making inventory tracking and maintenance scheduling a breeze.

KIS also offers unmatched after-sales support. Every StatCut 3000 comes with a 5-year warranty—the longest in the industry—and KIS's team of technicians is available for on-site repairs within 24 hours in Japan and 48 hours in major global cities. "We treat our clients like family," Mori says. "Last year, a client in Brazil had a blade break during a peak season. We flew a technician there with a replacement part—arrived in 36 hours, and they were back up and running the same day."

Beyond motor stator cutters, KIS produces auxiliary equipment like conveyor belts and sorting tables, all designed to work seamlessly with the StatCut 3000. For recyclers who value simplicity, reliability, and a personal touch, Kyoto Industrial Solutions feels less like a supplier and more like a trusted partner.

Rounding out our list is Hiroshima GreenTech Systems (HGS), a relative newcomer that's quickly making waves with its focus on automation and AI-driven recycling solutions. Founded in 2010 by a group of robotics engineers from Hiroshima University, HGS set out to revolutionize motor recycling by reducing human intervention—and their motor stator cutter equipment, the AutoStator Cutter X9, is leading that charge.

The AutoStator Cutter X9 is a marvel of automation. It features a robotic arm that loads stators onto the cutting bed, eliminating the need for manual feeding. The arm uses machine vision to scan each stator, adjusting the cutting parameters (depth, pressure, blade angle) in real time to ensure optimal results—even for stators with irregular shapes or damage. "We tested it with 1,000 randomly sourced stators—some rusted, some bent—and it achieved a 98% success rate in clean cuts," says Dr. Kenji Ito, HGS's chief technology officer. "That's better than most human operators can manage."

The X9's AI system also learns over time. It tracks which stator types (e.g., from old refrigerators vs. industrial motors) require specific settings and suggests optimizations, further improving efficiency. For large-scale plants processing thousands of stators daily, this automation translates to labor savings of 2-3 operators per shift—a significant cost cut.

HGS hasn't forgotten about integration, either. The AutoStator Cutter X9 connects with their motor recycling machines equipment, including the AutoShred 4000 (a 4 shaft shredder equipment for heavy-duty pre-processing) and the AutoSort AI (a machine learning-powered material separator). Together, these form a "lights-out" recycling line—operated by just one supervisor monitoring screens—capable of processing 1,500 stators daily with minimal human input.

Of course, all this tech comes with a higher price tag, but HGS offers flexible financing options and a "productivity guarantee": if the X9 doesn't meet its promised throughput within 6 months, they refund 10% of the cost. "We stand behind our machines," Ito says. "Our clients in China and the U.S. have seen ROI in under 2 years, which is impressive for automation equipment."

For recyclers looking to future-proof their operations with AI and automation, Hiroshima GreenTech Systems is the supplier of choice.
