## What are the factors affecting speed of dc motor?

Factors Affecting The Speed Of A D.C. Motor

• The flux Φ
• The voltage across the armature.
• The applied voltage V.

## On what factors does the speed of an induction motor depends?

Observation: From the above expression, the speed of an induction motor is depends upon the the supply frequency and the number of poles.

## What factors increase the speed of an electric motor?

The speed of rotation of the coil can be increased by:

• increasing the size of the current;
• using a stronger magnet;
• increasing the number of turns of wire in the coil;
• reducing friction between the coil and the axel it rotates on.

## What are the 4 stages of motor development?

The stages of motor learning are the cognitive phase, the associative phase, and the autonomous phase.

## What are the two factors influencing the speed of induction motor?

The rotating speed of an electric motor depends on two factors: its physical construction, and the frequency (Hz) of the voltage supply. Electrical engineers select the speed of a motor based on the needs of each application, similar to how the mechanical load determines the horsepower required.

## What are the four typical AC induction motor speeds?

A magnetic field is created in the stator poles that induces resulting magnetic fields in the rotor which follow the frequency of the changing magnetic field in the stator. Two pole AC motors operating at 60 Hz will always run at approximately 3600 rpm, and four pole AC motors will have speeds around 1800 rpm.

## Which induction motor has maximum speed?

Synchronous and full load speed of amplitude current (AC) induction motors

Speed (rpm)
Number of Poles Frequency (Hz, cycles/sec)
