Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors.

IC interfaces are semiconductor chips that are used to control and manage the sharing of information between devices

Specialty IC interface devices are specialty or proprietary products related to IC interface devices

IC bus interfaces and controllers or bus masters are interfaces between most standard parallel-bus microcontrollers or microprocessors and the serial bus

RS-232, RS-422, and RS-485 are standard interfaces approved by the Electronic Industries Association (EIA) for connecting serial devices.

Sensor interface and excitation IC chips are used as interfaces to sensors and other devices.

Motor speed controllers are electronic devices that control motor speed.
