DC Servomotors

Often used for small automation applications, such as pick-and-place machines, these servomotors deliver lots of power in a small package. With accurate positioning and fine motor control, they create rotary motion based on signals from a drive (sold separately). The commands for speed and positioning are the same as those used for stepper motors, so you can upgrade your system without the hassle of reprogramming it. As these servomotors move, their encoder relays the shaft’s distance, direction, and speed back to the drive. The drive increases your system’s efficiency by taking the electrical signal from the encoder and dynamically adapting the motor’s movements, also accounting for inconsistent loads and unexpected forces.

Maximum Torque—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.

Servomotor Drives

Drives have several control modes that power the motor—step and direction, position, speed, or torque. Use a computer to set motion parameters and calibrate the servomotor to your system. After initial setup, you can use a separate controller, such as a programmable logic controller (PLC), microcontroller, or indexer. A brake resistor protects the drive from regenerated electricity as the motor slows or stops.

DC Servomotors with Integrated Drive

A built-in drive simplifies your servomotor setup, removing the need for cable between the motor and drive. DC servomotors are often used for small automation applications, such as pick-and-place machines, because they deliver lots of power in a small package. This system includes a motor, encoder, and drive for accurate positioning and fine control over speed and position.

These servomotors use the same step and direction commands as a stepper motor, so you can upgrade your current stepper motor system with this system. Use a computer to set up and calibrate the motor to your system. After initial setup, use a separate controller, such as a programmable logic controller (PLC), microcontroller, or indexer. The encoder relays distance, direction, and speed back to the servomotor. Based on this feedback, the servomotor dynamically adapts its movements to increase system efficiency.

Servomotor Power Supplies

Power supplies are designed to power servomotors, so they have tightly controlled voltage and high peak current output to support high performance motor control. They are capable of handling or dissipating regenerated energy as the motor slows or stops.

Stepper Servomotors with Integrated Drive

Simplify your servomotor setup—these servomotors have a built-in drive, removing the need for cable between the motor and drive. They create high torque at low speeds like traditional stepper motors but with greater torque performance and positioning reliability.

These servomotors accept step and direction, position, speed, torque, or sequencing commands. Use a computer to set up and calibrate the motor to your system. After initial setup, use a separate controller, such as a programmable logic controller (PLC), microcontroller, or indexer. You can also store target positions with speeds and accelerations in the drive and then trigger each sequence with minimal input from a controller. The encoder relays distance, direction, and speed back to the servomotor. Based on this feedback, the servomotor dynamically adapts its movements to increase system efficiency.

Maximum Holding Torque—Holding torque is the force needed to move the shaft out of position when it is stationary. Torque generally decreases as speed increases.

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.

Accessories for Servomotors

Servomotor Drives


Drive	Keypad

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.

Servomotor Gear Boxes

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.

Speed Reducers for Position- and Speed-Control Motors

Pair these speed reducers with stepper and servo motors in position- and speed-control applications. Helical gears provide exact positioning and smoother travel than our other speed reducers. Attach to a motor to transmit motion parallel to the motor shaft while reducing speed and increasing torque.

IP65 Enclosure Rating—They meet IP65 for protection from washdowns.

Radial Load Capacity—Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to shaft, such as pulleys and sprockets.

Stepper Servomotors

Combine the high torque at low speeds that traditional stepper motors are known for with the greater torque performance and positioning reliability of a servomotor. They create rotary motion based on signals from a drive (sold separately). As these servomotors move, their encoder relays the shaft’s distance, direction, and speed back to the drive. The drive increases your system’s efficiency by taking the electrical signal from the encoder and dynamically adapting the motor’s movements, also accounting for inconsistent loads and unexpected forces.

Servomotor Drives

Drives have several control modes that power the motor—sequencing, position, speed, or torque. You can program target positions with speeds and accelerations in the drive to trigger sequences with minimal input from a controller. You can also use a computer, programmable logic controller (PLC), microcontroller, or indexer to set motion parameters, tune the motor to your mechanical system, and stream multiple commands to the driver to carry out complex motion sequences.
