Electric Motor Drives
A Motor Drive is a system that varies the motor electrical input power to control the shaft torque, speed, or position. The motor drives can be classified into the following categories:
Application specific drive — designed to run a specific motor in a specific application (
e.g., variable speed pump drive).
Standard drive — designed as a general-purpose motor speed controller capable of running a variety of motors within a given power range.
Servo drive — designed to deliver accurate and high dynamic control of position, speed, or torque down to zero speed. Typically used in automation applications.
High performance servos — designed to deliver best in class accuracy and connectivity. Typically used in CNC and pick and place machines.
