Motor ratings that drive the sizing decision
The SH31003M01A2000 delivers 1500 W continuous power with a continuous stall torque of 8 N.m across 115...480 V three-phase supplies — the torque you get at zero speed for holding or positioning without a brake. Nominal torque and speed shift with the supply voltage: at 400 V three-phase you get 7 N.m at 2000 rpm, while 480 V three-phase yields 6.76 N.m at 2400 rpm. The peak stall torque of 28.3 N.m handles short-duration acceleration events, but the drive must supply 14.7 A peak to reach it.
Encoder feedback and connection for commissioning
The absolute single-turn SinCos Hiperface encoder provides position feedback without a homing sequence on power-up — the drive reads the absolute position within one revolution. This eliminates the need for reference switches in single-turn applications like rotary indexing tables. The rotatable right-angle connector lets you route the power and feedback cables in the direction that best fits the cable tray or drag chain — useful when the motor mounts in a tight axis envelope. Natural convection cooling means no fan or compressed air is required, but in a sealed cabinet with other heat sources, the ambient temperature around the motor must stay within the 130°C copper hot limit to avoid winding damage.
Mounting interface and mechanical integration
The 100 mm international standard flange with a 95 mm centring collar and 3.5 mm depth gives a repeatable pilot fit — the motor registers into the gearbox or machine frame without shimming. Four 9 mm mounting holes on the flange bolt pattern secure it. The smooth shaft (no keyway) is 19 mm diameter with a 40 mm engagement length and a 6 mm key width — you need a keyed coupling or a clamping hub to transmit the 8 N.m continuous torque without slipping. The shaft end is plain, so no external brake hub is fitted. Overall length is 240.5 mm from the mounting face to the rear of the encoder housing — check the axis clearance before committing the mechanical layout.
Environmental protection and load limits
IP54 with the shaft bushing without seal ring, IP65 with the seal ring fitted — the motor body and shaft bushing both meet IP65 per IEC 60034-5 when the seal is in place. This suits washdown zones in food processing or machining coolant environments. Maximum radial force on the shaft is 1050 N at 1000 rpm, dropping to 660 N at 4000 rpm — the bearing load capacity decreases with speed. Axial force is limited to 160 N. Exceed these and the bearing life shortens or the shaft deflects.
Electrical parameters for drive matching
Stator resistance is 5.3 Ohm and inductance is 17.4 mH — these set the electrical time constant and influence the drive's current regulator tuning. The torque constant of 2.35 N.m/A at 120°C lets you calculate the current required for a given torque target, accounting for winding temperature. Back EMF constant is 148 V/krpm at 20°C — at 2000 rpm the motor generates 296 V back EMF, which must stay below the drive's DC bus voltage to avoid regeneration overvoltage trips. The continuous stall current of 3.4 A is the thermal baseline for sizing the drive's continuous rating. Nominal output power ranges from 410 W at 115 V single-phase to 1700 W at 480 V three-phase — the motor's power capability depends on the supply available at the machine. The 1500 W continuous rating is achieved at 400 V three-phase.
The sizing reference SH31003M ties this motor to the SH3 series for drive selection and application engineering documentation.
