Why the holding brake and encoder choice matter for your axis
The SH31002P0AF3000 carries a holding brake rated at 9 N.m — enough to lock a vertical load or keep a stopped axis from drifting when the drive is disabled. That brake pull-in power is 12 W, so budget a 24 VDC supply capable of that inrush if the brake is released via a separate contactor. The absolute single-turn Hiperface DSL encoder means the drive knows the motor shaft position the instant power comes on — no homing sequence, no reference run. For a machine that must resume position after a power cycle, that saves a cycle-time hit on every restart.
Speed and torque across supply voltages
Nominal speed depends on the supply: 2000 rpm at 230 V single-phase, 4000 rpm at 400 V three-phase, 4800 rpm at 480 V three-phase. If your line runs 400 V three-phase, you get the full 1930 W nominal output; on 230 V single-phase that drops to 1090 W. Make sure the drive feeding this motor is rated for the voltage you actually have on the bus. Continuous stall torque is 5.8 N.m across the 115-480 V three-phase range, and peak stall torque hits 18.3 N.m — useful for short acceleration bursts. The torque constant is 1.21 N.m/A at 120 °C copper temperature, so the drive current limit should be set to protect the motor windings during sustained overloads.
Mounting and environmental fit
The motor flange is 100 mm with a 95 mm centring collar and 9 mm mounting holes — standard IEC frame that mates with common gearboxes and mounting brackets. The smooth shaft (19 mm diameter, 40 mm length) means the coupling must use a clamping hub or set-screw; no keyway to transmit torque directly. IP65 on the motor body with IP54 at the shaft bushing (without the shaft seal ring). In washdown or wet environments, fit the optional shaft seal to keep moisture out of the bearing cavity. Natural convection cooling — no fan, so the motor relies on the mounting surface and ambient airflow to shed heat.
