Welcome to the official website of Changzhou Hemm Intelligent Technology Co., LTD
By introducing a new winding structure, the core-free motor eliminates power consumption due to iron damage, making it particularly suitable for high-speed applications. In addition, there is no longer a stopping torque, so high-precision applications require such motors.
