30030 Motor Speed and Torque

Tachometer

Instrument designed to measure motor speed.

The amount of torque that a motor must generate at its shaft to drive the device it is driving is called the:

Load

The relationship between the torque input and output of a gear drive depends on

Gear ratio

When a motor is ___, the speed will decrease drastically from its rated speed.

Overloaded

If a gear attached to a load has more teeth than the gear attached to the motor, the speed of the load will be

Less than the speed of the motor

Torque is developed in an electric motor because of

Interaction of different magnetic fields
