Maintenance method analysis of dc motor controller

Dc motor controller in use may be a failure, and so on and so forth, so the need for repair work. Below small make up to introduce the maintenance method of dc motor controller. The resistance of the resistance method, is to use a multimeter, for dc motor controller circuit, contact a method of measuring. Voltage method: is the use of dc motor controller in the multimeter voltage profile, to inspect the circuit voltage value of a method. Current method: is the current in a circuit to measure can be conformed to the normal, to understand the cause of the failure. Above repair method of several kinds of dc motor controller is introduced, we can draw lessons from it.
