Motor specs that decide the drive match
The SH30702P1AF3100 is a three-phase servo motor from the SH3 series (Lexium 32 family). Its nominal output power is 1130 W at 400 V or 480 V three-phase supply, dropping to 610 W at 230 V single-phase — so the drive's power rating must match the supply voltage you're feeding it. Nominal speed shifts with the line voltage: 3000 rpm at 230 V single-phase, 6000 rpm at 400 V three-phase, and 7200 rpm at 480 V three-phase. The nominal torque follows the same pattern — 2.1 N.m at 230 V, 1.8 N.m at 400/480 V. The peak stall torque is 7.6 N.m across the 115...480 V three-phase range, which is the short-term overload headroom for acceleration or load transients. Continuous stall torque is 2.04 N.m at 115...480 V three-phase — this is the torque the motor can deliver at zero speed indefinitely without overheating. The continuous power rating of 1130 W sets the thermal limit for sustained high-speed operation.
Encoder, brake, and feedback — what's inside
The encoder is an absolute single-turn Hiperface DSL — a digital serial-link protocol that carries position and temperature data over a single cable pair. No battery backup needed for single-turn position; the drive reads the absolute position on power-up. The holding brake is integrated, rated at 3 N.m static holding torque with a pull-in power of only 7 W. That low holding power means minimal heat bleed into the motor housing during standstill. The brake is spring-applied, power-released — it engages when the drive's brake control signal drops out, so a power loss locks the shaft. Electrical connection options include a rotatable right-angled connector and a quicklock straight connector — both are IP65-rated when mated, giving flexibility for cable exit direction in tight cabinets or moving cable tracks.
Mounting, shaft, and mechanical limits
The motor flange is 70 mm (international standard), with a centring collar diameter of 60 mm and depth of 2.5 mm. The four mounting holes are 5.5 mm diameter — standard M5 bolt pattern. Overall body length is 213 mm. The shaft is 11 mm diameter, 23 mm long, with a parallel key (key width 4 mm). The shaft end is keyed — not a smooth shaft — so the coupling or pulley must have a matching keyway. Maximum radial force is 990 N at 1000 rpm, and maximum axial force is 160 N — stay within these for bearing life, especially with belt drives or overhung loads. Cooling is natural convection — no fan or forced air required.
Electrical parameters for drive tuning
Stator resistance is 4.2 Ohm and stator inductance is 21.3 mH — these set the electrical time constant and are needed for the drive's current-loop autotuning. The torque constant is 0.7 N.m/A at 120 °C (copper hot), and the back EMF constant is 48 V/krpm at 20 °C — both critical for the drive's velocity-loop gain calibration. The motor has 3 poles (not pole pairs — the evidence states 3 motor poles, which is unusual; a 3-pole motor is a 2-pole equivalent in synchronous terms). The winding insulation class is rated for a copper temperature of 130 °C.
