What are motor controller chips and motor controller modules?

The motor controller chip is a chip integrated with CMOS control circuit and DMOS power device, which could form a complete motion control system with the main processor, motor and incremental encoder. It can be used to drive inductive loads such as DC motors, stepping motors and relays.

The driving modules of motors usually include transistor module, thyristor module and IGBT module. Of course, the integrated driving module is also used for small micro-special motors.

Main functions of motor controller chip and motor controller module
The motor controller chip is controlled by standard TTL logic level signal, which has two enabling control terminals to allow or prohibit the device from working without being affected by input signal, and has a logic power input terminal to make the internal logic circuit work at low voltage. An external detection resistor can be used to feed back the variation to the control circuit.

The driving circuit converts the signal from the information electronic circuit into a signal that can be applied between the control terminal and the common terminal of the power electronic device to turn it on or off according to the requirements of its control target.

For semi-controlled devices, it is only necessary to provide on-control signals, while for fully-controlled devices, it is necessary to provide both on-control signals and off-control signals, so as to ensure that the devices are reliably turned on or off as required.
