Through a rich lineup of standard products and customized products fully tailored to customer needs, we offer drive motors that humans can operate as they wish
Our direct drive motors come in various sizes measuring 80 to 630 mm in outer diameter. The lineup of standard products includes over 50 models to accommodate a variety of needs such as fast response, high rigidity, thinness and high-speed rotation. Through customized products built on our diverse standard products to meet customer requests, we offer drive motors that humans can operate as they wish.
Moreover, we manufacture all the components internally, including motors, servo drivers and encoders, allowing us to deliver drive systems that can bring out the full potential of the motor. That’s one of our major strengths.
A rich product lineup of over 50 models to meet individual needs
We boast a diverse lineup of motors, which only a servo drive manufacturer committed to accommodating customer needs can offer. A variety of series is available whose rated torque ranges from 1.6 to 7500 N·m.
High-accuracy positioning is possible
Positioning accuracy
- ±10 to 15 arcsec (when the absolute position compensation option is used)
Repetitive positioning accuracy (during reciprocating motion)
- ±1 to 2arcsec
Special tests allow even out-of-spec items to be checked
- Positioning accuracy measurement using laser length measurement and a high-accuracy encoder
- Rotation runout accuracy measurement using a true sphere
- Load displacement amount measurement
- Speed stability, output torque accuracy measurement, etc.
Industry’s fastest response can boost production capacity
The high-response type τDISC HD-s Series features an ultra-high torque and ultra-low inertia structure, enabling increased takt time performance.

High torque and compactness
The standard type τDISC ND-s Series boasts the highest torque density in the industry as it features increased torque density and an optimized thermal structure and magnetic circuit, among others. These motors offer high torque while being compact in size.
High-response, thin, high-torque motors
The thin type τDISC ND-u Series offers motors that are 39.5 mm in thickness. The lineup includes two types of motors: one is 180 mm in outer diameter and the other 250 mm. The motor whose outer diameter is 250 mm has much higher rated torque than motors of the same size from other companies. Even the motor with an outer diameter of 180 mm provides rated torque that is the same as or higher than that of motors from other companies that are 250 mm in outer diameter. Moreover, the overwhelmingly high power rate enables fast response.
