Stepper Motors
These stepper motors are good for precise, repetitive movements, such as those made by the head of a 3D printer. Similar to the hands of a clock, their shaft turns in small, equal increments. When the shaft stops, it holds its position even when a counteracting force is applied to the load. You can control the position of the load without having to configure encoders or sensors. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.
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.
All motors require a controller and driver (not included).

Wet-Location Stepper Motors
To precisely position loads in automated systems that are frequently rinsed, these stepper motors are IP65 rated to seal out water. Their shaft turns in small, equal increments, similar to the hands of a clock. When the shaft stops, it holds its position even when force is applied to the load. This means you don’t need to configure encoders or sensors to control the position of the load. All are hybrid bipolar stepper motors, so they have more torque, precision, and efficiency than other stepper motors.
Holding torque is the force needed to move the shaft out of position when it’s stationary. When the shaft is in motion, torque generally decreases as speed increases.

Speed-Control Motors
Maintain speed automatically. These motors come with a speed control with a feedback sensor that adjusts power to maintain your set speed. They combine the speed control characteristics of permanent magnet brushless DC motors with the convenience of AC power—an integrated inverter means they operate on 120 volts AC.
Motors are rated for continuous duty and mount at any angle. Shaft is keyed and comes with key stock. Use the switch on the speed control to set clockwise or counterclockwise rotation.
All have manual overload protection—an LED on the speed control indicates when the overload protection is triggered; use the switch to reset. Control also has an on/off switch and a speed adjustment knob. Panel mount the control up to 10 feet from the motor—it comes with a 10-ft. cable for connection.
