Asaba Engineering has developed what it claims is the shortest length and the lightest weight coreless DC motor for motion control applications.
Asaba Engineering has developed what it claims is the shortest length and the lightest weight coreless DC motor for motion control applications.
The Model YDC-20 is a high efficiency (87.21%) motor that is just 18.9mm long with an inner diameter of 20mm, and weighs only 28g.
Based on Asaba's patented coil winding technology, rated voltage is 6V, minimum starting voltage is from 0.03V and no load current is only 7.9mA.
Starting torque is 26.55mNm and the torque constant is 14.76mNm/A.
A high ratio gearbox is not required, thereby reducing total system costs.
A double shaft for an encoder is available as option.
Applications that benefit from quick response, low power consumption and miniature size include robot actuators, mobile medical products and miniature pumps.
