Constant-Speed AC Gearmotors
Achieve precise, constant speed for timing and positioning applications. Also known as synchronous gearmotors, these gearmotors use a frequency of 50/60 Hz to maintain speed and torque.

AC Servomotors
Good for high speeds with fast accelerations, these servomotors are often used in automated assembly, material handling, and packaging applications. These motors require a low amount of force to stop or start, commonly referred to as low inertia, so they respond to position commands quickly and can rapidly accelerate and decelerate.
Pair a servomotor and drive (sold separately) for accurate speed and position control. The absolute encoder built into the motor knows the exact position of the shaft at startup and relays distance, direction, and speed back to the drive. Based on this feedback, the drive dynamically adapts the motor’s movements and increases system efficiency. A brake resistor protects the drive from regenerated electricity as the motor slows or stops.
Drives can be quickly set up and programmed to control position, speed, and torque from a computer or programmable logic controller (PLC). These drives only require one cord to connect to the motor and encoder. Once connected, the drive recognizes the motor and automatically begins startup. Use the keypad to start the motor, run diagnostics, and edit motion parameters directly from the drive. Drives also include safe torque off (STO) functionality, which prevents power from going to the motor during an emergency stop or maintenance.
Gear boxes reduce the speed and increase the torque output of your motor. These planetary gear boxes have low backlash, which allows them to maintain a high-level of precision when transmitting motion from your servomotor. They also have hardened steel gears that withstand fast accelerations in dynamic applications. They come permanently lubricated, so there is no need to add or maintain oil or grease.

Torque generally decreases as speed increases. Use a torque-speed curve to confirm which motor will work for your application. Click on a part number and select "Product Detail" to view the curve for a motor.
