Gear-in motor

Gear-in motor



Compared to conventional external gears, the gear built-in motor is less than 50% in volume ratio.
High torque is realized by the built-in gear while being lightweight and compact.
Long life
The model with the encoder and the brake will be developed sequentially.

Why has the gear-in motor not existed so far?

Because our motor is coreless, there is a hollow structure. Therefore, there is a space where the gear part enters.
gear 01

If coreless motor, any maker can make it?

No, keep the conventional structure and reduce the gear, it will be short-lived!!

➡ Proprietary world patent technology to put the gear in a small space 

      without sacrificing life is realized!
