Canton has wholesalers and manufacturers for electric motor controls. A motor is a device that converts electrical energy into mechanical energy. A motor control is an insturment or a device that regulates the working of an electric motor. Instead of a single device, it can be a group of devices. Some of the functions of a motor that can be controlled include controls for starting and stopping the motor, the reverse or forward rotation of the motor parts, speed and/or torque regulation, and protection against faults and tripping up. Some of the control parts include motor starters, adjustable-speed drive (ASD) or variable-speed drive (VSD), Intelligent Motor Controls (IMCs), and an assemblage of intruments called a motor control center. These are manufactured in large scale, depending on the type of motor and the function needed. Wholesalers in Canton sell in bulk, at lower than retail rates. They may also offer a distribution service for the consignment.
