4TK10GN-AUL Oriental Motor Torque Motor

The Oriental Motor Torque Motors are designed to provide high starting torque and sloping characteristics (torque is highest at zero speed and decreases steadily with increasing speed), and operate over a wide speed range. They also provide stable operation, especially in the low speed range or under a locked rotor condition.

The motor torque is approximately proportional to the square of the voltage, allowing easy speed control simply by changing the voltage of the power supply.

In an application where an object is released continuously at a constant speed and wound up with constant tension, the torque must be doubled and the speed must be halved if the diameter of the winding spool is doubled.

Unlike induction motors or reversible motors, torque motors are designed to provide a stable torque even under stall conditions or at very low speeds (nearly stalling). They are suitable for pushing applications that require static torque, or for loads that are usually under a locked rotor condition but are under stall conditions at the end of processes. The motors can operate continuously at 60 VAC or less. When used at voltages above 60 VAC, the motors are rated for limited duty. The motor has a 5-minute rating at 115 VAC.

By using the motor in the braking region of the speed-torque characteristics, it can serve as a brake. Constant tension operation can be achieved by applying a DC voltage.
