Servo Motors

Servo motors are rotary actuators that allow for precise control of angular or linear position, velocity, and acceleration. Their size and energy efficiency make them suitable for a number of applications like robotics, RC toys, and more.

Servo solutions & systems consist of a motor coupled to a sensor for position feedback with a servo drive to complete the system. The drive uses the feedback sensor to precisely control the rotary position of the motor.

Servo Motor Types:

Servo motors come in two main types: brush and brushless. Both servo motor types operate in a continuous torque range as well as a peak torque range. Peak torque can be much higher than continuous torque but can only be achieved for short periods of time. By comparison, continuous torque can be reached throughout the regular operation of a servo motor.

Brushed servo motorsBrushed servo motors

Brushed Servo Motors 

Have winding in the rotor and permanent magnets on the stator. Carbon brushes and a mechanical commutator provide a current path through the windings to achieve motor torque. A DC motor will continuously rotate if a DC power source is applied across its terminals. Reversing the polarity will cause the motor to reverse direction.


Brushless NEMA servo motorsBrushless NEMA servo motors

Brushless Servo Motors (NEMA)

Have windings in the stator and permanent magnets attached to the rotor. No brushes are used. Motor rotation is achieved by means of electrical commutation performed by the drive. Brushless servo motors provide high acceleration, high torque, and no maintenance. 


Direct drive motorsDirect drive motors

Direct Drive Motors

Any motor, rotary or linear, in which the load is directly coupled to the motor without mechanical transmission elements such as gearboxes, rack and pinions, or belt and pulley systems.  In this system, the motor directly drives the load. 


Flat / Pancake Motors

When space is at a premium, Maxon Brushless Pancake Motors are the solution. The electronically commutated Maxon EC flat motors are particularly noteworthy for their excellent torque handling characteristics, high performance, extremely wide speed range and, of course, their unsurpassed service life.
