How to Select the Type of Motor

The basic contents required for motor selection include:

The type of load driven, rated power, rated voltage, rated speed, and other conditions.
 

Load type · DC motor · Asynchronous motor · Synchronous motor

For production machinery with stable load and continuous operation without special requirements for starting and braking, it is advisable to prioritize the use of ordinary squirrel cage asynchronous motors, which are widely used in machinery, water pumps, fans, etc.

Production machinery that requires high starting and braking torque due to frequent starting and braking, such as bridge cranes, mine hoists, air compressors, irreversible rolling mills, etc., should use wound asynchronous motors.

In situations where there is no requirement for speed regulation and constant speed or improvement of power factor is required, synchronous motors should be used, such as medium and large capacity water pumps, air compressors, elevators, mills, etc.

For production machinery that requires a speed regulation range of 1:3 or above and requires continuous, stable, and smooth speed regulation, it is recommended to use separately excited DC motors or squirrel cage asynchronous motors or synchronous motors with variable frequency speed regulation, such as large precision machine tools, gantry planers, rolling mills, elevators, etc.

For production machinery with large starting torque and soft mechanical characteristics, series excited or compound excited DC motors shall be used, such as tramcars, electric locomotive, heavy cranes, etc.

Generally speaking, providing the type of load driven, rated power, rated voltage, and rated speed of the motor can roughly determine the motor.

But if we want to optimize to meet the load requirements, these basic parameters are far from enough.

The parameters that need to be provided include: frequency, working system, overload requirements, insulation level, protection level, moment of inertia, load resistance moment curve, installation method, environmental temperature, altitude, outdoor requirements, etc. (provided according to specific circumstances)
