Dc motor controller is one of the main types of motor controller.
Below small make up for the advantages and disadvantages of the dc motor controller.
Voltage waveform is better, the controller of dc motor in use is affected by electromagnetic interference.
Has a wide range of speed and speed control features smooth edge.
Due to the strong ability of overload, make it at the time of starting and braking torque is larger.
The dc motor controller has these advantages, but because of commutator, so in the relatively high cost.
