Stepper Motors with Integrated Motion Control

With a built-in controller and drive, these stepper motors come ready to program and operate. Connect them to a computer and use the free downloadable software to set them up. After that, the controller can store and run programs on its own. The controller communicates to the drive which directs the motor’s shaft to move in small, equal increments. When the shaft stops, it holds its position even when a counteracting force is applied to the load. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.

For the Manufacturer User Manual, click on a part number and select Product Detail.

Encoders—When relative positioning is critical, such as coordinating motion in a multi-axis system, choose a motor with an encoder. The encoder monitors the position of the shaft and reports back to the controller.

Maximum Holding Torque—Holding torque is the force needed to move the shaft out of position when it is stationary. When the shaft is in motion, 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.

Full Step Increment—Full step increment is the rotation of the shaft from one position to the next. A smaller full step increment means the rotor has more teeth, producing smoother and more precise motion. 1.8° is considered standard.

Step Resolution—You can adjust the step resolution down to _1/256 of a full step, which translates to 51,200 microsteps per revolution. Increasing the number of steps directs an even more precise position and reduces the step-step-step motion to mimic a smooth, continuous rotation. The higher the number of step resolution settings, the greater the flexibility you have for determining the size of the motor’s step.

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.

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.

Precision Beam Couplings


Spiral Cut

Machined with slits, these one-piece couplings flex to transfer full torque (zero backlash) and compensate for tiny misalignments.

Spiral Cut—Long slits along the surface help the coupling flex and handle greater misalignment than parallel cut couplings. They're also less rigid, so they're best used with light duty machinery, such as encoders and stepper drives. Also known as helical beam couplings.

303 Stainless Steel—More corrosion resistant and stronger than aluminum couplings, these withstand mild cleaning solutions, such as acetone and ammonia.

Aluminum—Lightweight and corrosion resistant.

Clamp-On Shaft Mount—Grip shafts evenly without marring them and hold tighter than set screws. Tighten the clamping screws to secure.

Set-Screw Shaft Mount—Screws dig into your shaft for a secure hold.
