  The working principle of  brushed dc motor controller : The electric energy of the DC power supply enters the armature winding through the brush and commutator, generating the armature current. The magnetic field generated by the armature current interacts with the main magnetic field to generate the electromagnetic torque, making the motor rotate and drive the load. Due to the existence of brush and commutator, brush motor has complex structure, poor reliability, many faults, large maintenance workload, short life, commutator spark easy to generate electromagnetic interference. What we are doing?    1. Customer provide a  brushed motor speed controller  BOM, we offer our quotation in 2-3 days.    2. We suggest alternative components to customer, to help to reduce the cost, and delivery time.  ...
