DC motors are most commonly used in variable speed and torque applications. DC Servo Motors - Servo motors are generally small, powerful for their size, and easy to control. Common types of DC servo motors include brushless or gear motor types. Its job is to convert an input to an output of lower RPM and higher torque. Linear Motors - A linear motor generates force only in the direction of travel.
Linear motors are capable of extremely high speeds, quick acceleration, and accurate positioning.
Stepper Motors - A stepper motor uses a magnetic field to move a rotor. Stepping can be done in full step, half step or other fractional step increments. Stepper motors provide precise positioning and ease of use, especially in low acceleration or static load applications. Motor Contactors - Motor starters and contactors are motor starting devices. A motor starter combines a contactor with overload protection.
