○ How to Read the Torque Motor Speed–Torque Characteristics

The motor torque generally varies in proportion to the square of the applied voltage.
When the voltage applied to the motor is changed, the speed–torque characteristic curve
(where torque is maximum at standstill and decreases as speed increases) shifts according to the voltage level.
If the voltage is adjusted to 100V, 80V, and 60V, and the load torque is T₀, the motor will rotate at speeds N₁, N₂, and N₃, respectively.
In this way, the rotation speed can be easily controlled simply by adjusting the voltage.
The speed–torque characteristic curve is used to determine whether continuous operation or intermittent operation is required.
For applications involving a locked (stall) condition, only the torque coefficient needs to be considered.
Temperature rise of the motor can become an issue during continuous operation.
In such cases, select a motor with sufficient output for continuous operation and adjust the voltage to control the torque and speed.

Wiring Diagram

・The direction of rotation is based on the viewpoint from the motor shaft end.
CW indicates clockwise rotation, and CCW indicates counterclockwise rotation.

● Cautions
・For single-phase motors, always switch the rotation direction after the motor has come to a complete stop.
・Attempting to switch rotation while running may result in failure to change direction or delayed response.

Spec.	You can purchase a gearhead set that matches the motor size and gear type. Please check the gearhead specification table to confirm the available gear ratios based on the motor flange number. [ ! ] Available gear ratios: for flange □42 → 1/3 to 1/60, others → 1/3 to 1/200. [Designation method] Gear ratio 1/30 → GH30	You can purchase a mid-gear set that matches the motor size.

Product Features

1. Wide Speed Control Range via Sloping (Speed–Torque) Characteristics
Torque motors provide high starting torque and sloping speed–torque characteristics, allowing easy speed control simply by adjusting the supply voltage.
(Motor torque generally varies in proportion to the square of the applied voltage.)

2. Suitable for Winding Applications
Ideal for winding systems where material must be unwound at a constant speed and rewound under constant tension.
When the diameter of the winding spool doubles, the required torque must be doubled, while the speed must be reduced to half.

3. Can Be Used as a Brake
By operating the motor in the braking region of the speed–torque characteristics, it can function as a brake.
Applying DC voltage enables tension control operation, maintaining constant tension.
