How are Electric Motors Rated?

Motor Power Rating Definition

Motor power rating is the measure of the required supply voltage and maximum current for a motor to operate efficiently without breakdown.

Efficiency and Damage Prevention

Proper motor power rating ensures maximum efficiency and prevents frequent damages from overloading.

Thermal Loading

The output power of the motor is linked to temperature rise, known as thermal loading, requiring careful heat management.

Ventilation System

A well-designed ventilation system ensures ideal thermal dissipation, balancing generated and dissipated heat.

Motor Duty Class

Calculating motor ratings for various duty classes helps in selecting and operating motors effectively.
