SM2862-5155

SM2862-5155 is a Sanyo Denki motor in the F SANMOTION Stepping Motors series. It uses a bipolar winding configuration and operates with a bipolar current of 4 A. The winding resistance is 0.83 Ω, which determines resistive voltage drop and power loss, while the 6.4 mH winding inductance affects current rise time during step commands. Its back EMF constant is 175 V/krpm, indicating the voltage generated in relation to rotational speed. The insulation voltage is 250 VAC, providing the rated electrical isolation level.

The motor has a 1.8° step angle, allowing 200 full steps per revolution. Its bipolar holding torque is 700 N·cm, indicating the torque available to maintain a stationary shaft position when energized. The theoretical acceleration is 23,300 rad/s², while the rotor inertia is 0.0003 kg·m² and represents the rotor’s resistance to changes in speed. The single-shaft configuration provides one mechanical output shaft, and the shaft diameter is 14 mm for coupling to a load.

The body length is 96.5 mm, and the motor has a mass of 2.9 kg. Its IP43 ingress-protection rating provides protection against solid objects larger than 1 mm and water spray at angles up to 60° from vertical.
