Make robot development in Japan more free! A gearless structure in-wheel motor realized at an overwhelmingly low cost.
I want you to challenge the development of smart robotics in a more accessible way." The 'HSM Series' from Crew Co., Ltd. was born from this strong desire and is an in-wheel motor designed for AGVs, AMRs, and autonomous mobile robots. In-wheel motors have very high component costs, which have become a significant "burden" in Japan's development scene. Our company has directly collaborated with ODM partners to achieve overwhelming cost performance, offering products at "less than half the effective price" compared to reliable domestic manufacturers' equivalents. This product adopts a "gearless direct structure" that does not use gears. While it is not suitable for transporting heavy loads, it boasts "zero risk of gear damage," "overwhelming quietness," and "vibration resistance and high rigidity." Additionally, all products come standard with magnetic encoders, allowing for precise control down to the millimeter as desired. We provide the strongest mobility platform for small smart robots and next-generation mobility under "300 kg.

Furthermore, pressure and characteristic tests are conducted on all units, ensuring complete traceability from manufacturing history to inspection data via the QR code on the back of the motor.
Price information
We have achieved an overwhelming low price of "less than half the actual price" compared to equivalent products from reliable domestic manufacturers. Without compromising on the smart design of the robot due to budget constraints, we enable speedy PoC (proof of concept) and prototype development using wheel units with gearheads. We can provide a sample from a single unit. As this is an overseas product, additional shipping costs may apply when arranging the sample. Please request a detailed quote for pricing.

Applications/Examples of results
This product is aimed at all engineers developing mobility and smart robots with a total weight of "300kg or less." 【Main Use Cases】 Addressing labor shortages: As a base for lightweight material transport AGVs within factories, book transportation in libraries, and guidance/serving robots in hotels. Attractions and entertainment: For small personal mobility devices that children can safely ride and play on in amusement parks and commercial facilities. Verification and testing environment for next-generation technologies: Can be immediately implemented as a "base for demonstration experiments" to confirm compatibility and operation of AI, autonomous driving software, and various sensors. 【Flexible Customization and Support】 The catalog is merely a "starting point." We accept original customizations from one unit to match your ideal robot, including voltage changes (48V to 24V), tire material changes, shaft shape changes, and the addition of electromagnetic brakes. We will work alongside you as "crew" until the actual machine is operational.
