Position-Control DC Motors with Integrated Driver and Controller

An all-in-one solution for precise positioning, these motors are often used to move CNC heads and other automated systems. Connect to a computer with the included cable to program them—they can store up to 16 settings. Also known as stepper motors, they turn their shaft in small increments (steps).

Motors with a sensor and encoder track how far the shaft rotates and signals to the driver to move the motor if necessary. Closed loop feedback detects and corrects the motor if it becomes overloaded or loses power, making them more accurate than traditional stepper motors.

Position Control DC Motors, Drivers, and Controllers

Motor

Driver

Controller

Also known as stepper motors, these motors turn their shaft in discrete increments for precise position control. Shaft can turn clockwise or counterclockwise.

Motors require drivers and/or controllers (sold separately) to operate.

Drivers convert voltage into pulses that rotate the motor shaft. All drivers require a controller, PLC, or computer to function; they're compatible with all computer operating systems. They come with a data cable, except 6627T59 and 6627T62 do not come with a data cable. 6627T81 comes with instructions.

Controllers store programs to run the drivers. They're compatible with all computer operating systems. Controllers for NEMA 8, 11, 14, and 17 motors store up to 16 programs. They contain a driver. Controller for NEMA 23 and 34 motors stores 2 programs that it can run simultaneously. It requires a driver to operate (sold separately).

Speed-Control Motors

Motor

Control Face

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.
