Product Description:

The T402-011 is a compact DC servo motor produced by Sanyo Denki within the T SANMOTION Servo Motors series. It is intended for positioning and speed-regulated operation in industrial automation. The motor converts drive commands into precise shaft rotation so actuators, vision stages, or miniature conveyors can follow programmed motion profiles without mechanical overshoot.

This model delivers a continuous stall torque of 0.08 N·m, allowing it to hold a load steadily when the shaft is energized but motionless. The motor is rated for 0.023 kW of continuous mechanical output and has a nominal speed of 3000 rpm, providing a suitable power-to-size ratio for low-inertia axes. An armature supply of 20 V supports this operating point. The housing has a protection rating of IP43, protecting the motor against solid objects larger than 1 mm and water spray. Power and feedback connections use lead wires, and the supplied 1000 mm lead length allows the motor to reach a cabinet terminal block without intermediate splices. A D-shaped output shaft mates directly with compatible push-fit pulleys or gears, reducing the need for additional connection hardware. The shaft does not have an oil seal, so its interface should not be exposed to fluid spray. The motor also does not include a tachometer generator, so an external encoder is required when closed-loop speed feedback is needed.

During rapid acceleration, the motor can reach a peak stall torque of 0.42 N·m, supporting brief load surges without saturation. A flange diameter of 41 mm simplifies mounting on micro-machining plates, while a rotor inertia of 0.047 × 10⁻⁴ kg·m² enables a fast response to control signals with limited overshoot. The motor has a mass of 0.3 kg, adding minimal weight to moving stages while providing torque for small pick-and-place heads or laboratory instruments.
