Spindle Motors

Designed to run at high speeds with very little vibration, these motors often drive smooth, steady cuts in CNC machines. They’re brushless, so they run faster, last longer, and are more efficient than brushed DC motors. They also have a higher torque-to-weight ratio. You’ll need a brushless DC motor driver (not included) to power and control these spindle motors. They’re not compatible with automatic tool changers.

They come with an ER-11 collet for holding round-shank tools, such as router bits, drill bits, and end mills. Collets for larger shank sizes are sold separately.

Total Indicated Runout (TIR) Accuracy—Total Indicated Runout (TIR) is a measure of rotational smoothness—the lower the value, the less wobble a rotating tool will have and the more accurate it will be. When choosing a replacement spindle motor, you want one that has an equal or better TIR.

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.

Brushless DC Motors

Since there are no brushes to add weight and friction, these motors can achieve a higher torque-to-weight ratio, faster speeds, and better efficiency than DC motors with brushes. All motors require a driver to operate.

Round-face motors come with a connector that was used to test the motors during the manufacturing process. Before you can wire these motors to the terminals on their required driver, you will need to cut off the connector.

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.

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. 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—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.

Low-Profile Electric Positioning Slides with Automated Controls

Less than one-third the height of standard electric positioning slides, these slides push and pull small parts in electronics manufacturing, robotics, and other automated processes. They have a magnetic linear motor to generate fast and precise motion while taking up only a tiny footprint. With a controller and driver also included, they’re an all-in-one actuation system. Use them where extreme precision is needed—they have a repeatability of -0.5 to 0.5 microns, which is ¹⁄₅₀₀₀₀ of an inch.

Download free CME2 software during initial setup for easy, point-and-click programming. Controllers using CME2 can store and run sequences of up to 32 steps. For added speed and flexibility, these slides are also compatible with CPL, used to write advanced custom programs.

Dynamic load capacity is the maximum load slides can move. If you increase the speed, the dynamic load capacity decreases. Use a load-speed chart to confirm which slides will work for your application. Click on a part number and select "Product Detail" to view the chart.
