Motor Control
The electric motor is a device that converts electrical energy into mechanical energy, it uses electricity and magnetic field to produce torque to turn the rotor and hence give mechanical work.
Depending upon the application where the motor is used, the motors are controlled by computerised control systems, like solid-state logic controls, or programmable logic controllers (PLCs) to control and manage their torque, speeds, the work or energy delivered. Motor controllers can have many features of controlling a motor that may include but are not limited to starting, stopping, over-current protection, overload protection, reversing, speed changing, jogging, p lugging as well as sequence control. Motor Controllers range from simple to complex and can provide control for one motor or groups of motors.
Motors are broadly classified into two categories; AC Motors and DC Motors, based on the source of electrical energy used.
DC – Motor Types: Series, Shunt/Parallel and Compound based on the way the field coils and armature coil circuits are wired. Other types of DC Motors are the Permanent Magnet (PMDC) Motors and Separately Excited Motors.
AC – Motor Types: AC Induction Motors (also known as asynchronous motor) and Synchronous Motors. They are further classified by their applications like single phase, three phase, Squirrel Cage Induction, Dual Voltage etc.
