Four pointers for choosing an electric motor

The benefit of a DC motor is that it can produce a greater torque and its speed can be readily changed by varying the voltage. It works well with weights that need speed adjustments often, like hoists in mines and rolling mills in steel factories. However, the advancement of frequency converter technology has made it possible for AC motors to modify the frequency in order to change the rotational speed. Although the cost of an inverter motor is not significantly more than that of a regular motor, the cost of the inverter takes up the majority of the equipment, therefore brushed DC motors also have the benefit of being less expensive.
