10600 W continuous — the drive-match number
The SH32053P12F2000 is a three-phase servo motor rated for 10600 W continuous power. That is the figure your drive sizing software uses to match the motor to the amplifier — pair it with a drive that can deliver the continuous current at the bus voltage your line runs. Nominal speed depends on the supply you connect: 500 rpm at 115 V single phase, 1000 rpm at 230 V single phase, 2000 rpm at 400 V three phase, 2400 rpm at 480 V three phase. The motor is wound for a wide voltage range, but the rated torque shifts with the winding connection — 751.4 lbf.in at 115 V single phase down to 355.8 lbf.in at 480 V three phase.
Peak and continuous torque — what the numbers mean for the machine cycle
Peak stall torque is 2920.7 lbf.in (330 N.m) across the 115...480 V three-phase range. That is the short-duration overload available for acceleration, deceleration, or clearing a jam — the drive must be programmed to limit the peak current to 136.1 A and the duration to the thermal limit of the motor. Continuous stall torque is 835.5 lbf.in (94.4 N.m) at zero speed. This is the holding torque the motor can sustain without overheating — the holding brake adds another 80 N.m for power-off position holding, so the brake handles the static load while the motor handles the dynamic cycle.
Mechanical interface — shaft, flange, and mounting envelope
The shaft is 1.5 in (38 mm) diameter, 3.1 in (80 mm) long, with a 0.4 in (10 mm) parallel key. The motor flange is 8.07 in (205 mm) with an international standard flange pattern — mounts directly to a standard NEMA or IEC gearbox face without an adapter plate. Overall length is 21.2 in (538.5 mm). The centring collar depth is 0.2 in (4 mm), and the mounting holes are 0.6 in (14 mm) diameter. Allow clearance for the straight connector or the rotatable right-angled connector — the connector orientation can be adjusted on site to fit the cable exit path. IP rating is IP54 at the shaft bushing without the seal ring, IP65 at the motor body and shaft bushing with the seal ring fitted. For washdown or wet environments, specify the seal ring — the motor body itself is sealed to IP65, but the shaft exit is the leak path without the ring.
Feedback and braking — the control-loop components
The encoder is an absolute multiturn SinCos Hiperface type. This is a single-cable feedback protocol that carries position data over a sine/cosine analog channel plus a digital serial link — no separate encoder cable needed if the drive supports Hiperface. The multiturn count tracks absolute position over multiple shaft revolutions, so the machine does not need a home cycle after power loss. The holding brake is rated 80 N.m and is included with the motor. It is a spring-applied, electrically released brake — power to the motor releases the brake; power loss engages it. The brake torque is lower than the continuous stall torque (94.4 N.m), so the brake holds the load stationary when the drive is off, but the motor handles the dynamic torque during motion. The torque constant is 2.84 N.m/A at 248 °F (120 °C) hot copper temperature. The back EMF constant is 172 V/krpm at 68 °F (20 °C). These two constants define the motor's voltage-speed and current-torque relationship — the drive's current loop and velocity loop gains are tuned around them.
The motor is part of the SH3 series, with the sizing reference SH32053P. The same part, different passport: genuine is genuine regardless of which authorized region it came from, though the manufacturer warranty may be region-locked.
