Speed and torque across the voltage range
The SH30703M11F1200: This SH3 series motor delivers 3000 rpm at 400 V three-phase input, with nominal torque of 2.63 N.m and nominal output power of 880 W. At 480 V three-phase it reaches 3600 rpm and 1030 W, still with 2.63 N.m nominal torque. The continuous stall torque is 2.94 N.m across the three-phase voltage range, and the peak stall torque hits 11.3 N.m — useful for short acceleration bursts or overcoming static friction on a loaded axis.
Encoder and feedback — absolute single-turn Hiperface
The motor carries an absolute single-turn SinCos Hiperface encoder. Single-turn means position is known within one revolution after power-up — no homing routine needed on a rotary table or spindle that never rotates more than 360°. The SinCos analog track gives interpolated position for smooth low-speed regulation; the Hiperface protocol is common on Schneider and third-party servo drives. The connector is a rotatable right-angle or straight type, so the cable exit direction can be adjusted during installation.
Holding brake and mechanical limits
Fitted with a holding brake rated at 3 N.m static torque — enough to hold a vertical axis or tool changer at rest with the drive disabled. The maximum mechanical speed is 8000 rpm, well above the rated speeds, so the rotor and bearings are not the limiting factor if the drive runs field-weakening. Maximum radial force at the shaft is 730 N at 1000 rpm, derating to 400 N at 6000 rpm; axial force is limited to 80 N. The shaft is a parallel key design, 14 mm diameter, 30 mm length.
