Brushless DC motors have a permanent magnet rotor and a coil wound stator.

True

The efficiency of brushless DC motors makes them less expensive.

False

A servo DC motor does not involve a control circuit and position sensing unit.

False

A commutator is a method of applying electrical current to the windings and produces a steady rotating torque by reversing the current direction.

True

Self excited DC motors are further divided into shunt, series, and compound types.

True

In a shunt wound DC motor, the speed stays constant and does not deviate with varying mechanical loads.

True

A series wound motor can only work with AC voltage supply.

False

Actuators turn electrical signals into physical outputs.

True

Sensors and actuators are essentially similar devices that perform opposite functions.

False

Most of today's robotic systems are powered by hydraulic actuators.

False

Actuators turn electrical signals from control modules into physical outputs.

True

Sensors and actuators are essentially the same devices with different functions.

False

Most of today’s robotic systems are powered by hydraulic actuators.

False

Test your knowledge about actuators, which are key components in robotic systems, generating desired motion in servoed joints. This quiz covers the concept of electromechanical actuators and their application in today's robotic systems.
