Changzhou High-Efficiency Motors Co., Ltd.
We are a professional coreless brushless motor factory that provide high quality coreless brushless motor. By bringing new types of winding structure, coreless motor erase the power consumption due to iron loss, thus especially suitable for high speed application. Also, no detent torque exists any more so high accuracy application requres such type of motor.
