Front

Define 'Cradle mount' in motor installation.

Back

A cradle mount is a method of securing a motor using a cradle-like structure that supports the motor from below.

Front

What is a 'rigid-base mount'?

Back

A rigid-base mount is a method of mounting a motor directly to a solid base, providing stability and support.

Front

Explain the function of a 'rotor' in an electric motor.

Back

The rotor is the rotating part of the motor that interacts with the magnetic field to produce motion.
