What is No and and NC contact ? What is switch? What is motor? What is servo drive and Ac drive?

Question

Accepted Answer

NO and NC contacts are types of electrical switches. A motor is a device that converts electrical energy into mechanical energy. Servo and AC drives are motor controllers.

NO (Normally Open) and NC (Normally Closed) contacts are types of electrical switches used in control circuits.
A switch is an electrical component that can be used to make or break an electrical circuit.
A motor is a device that converts electrical energy into mechanical energy to perform work.
A servo drive is a motor controller that uses feedback to precisely control the position, velocity, and acceleration of a motor.
An AC drive is a motor controller that varies the frequency and voltage of the AC power supplied to a motor to control its speed and torque.

Accepted Answer

NC contact is normally closed ,NO normally open contact , switch operat and on off device emergency switch ,selectr which, stop ,start ,etc. swich used Motor is electrical energy convert to macanical energy called as motor drive is control device While a servo drive needs a command signal given to the motor in order to compare the real and desired position of the motor, a VFD directly controls the voltage and frequency supplied to the motor. VFDs are also known by other names such as AC drive, adjustable-frequency drive, inverter, and microdrive.
