Speed-torque envelope across supply voltages
The SH30702M12F1000 delivers a nominal speed of 3000 rpm at 400 V three-phase, but the same motor also runs at 750 rpm on 115 V single-phase, 1500 rpm on 230 V single-phase, and 3600 rpm on 480 V three-phase — the supply voltage directly sets the base speed, so the drive must be configured for the actual line voltage feeding the motor, not just the nameplate rating. Peak stall torque reaches 7.6 N.m across the full 115–480 V three-phase range, giving a 3.7× torque overload margin above the nominal rating — enough for rapid acceleration or breaking through a stuck load without tripping the drive.
Feedback and brake for vertical-axis control
The absolute multiturn SinCos Hiperface encoder reports both position and number of shaft revolutions on power-up, so the drive knows the exact machine position without a homing cycle — essential for pick-and-place or gantry axes where lost position after a power cycle means a crash. The holding brake delivers 3 N.m static torque, which holds the vertical axis load when the motor is unpowered — the brake engages automatically on drive disable, so the load won't drift during a power loss or emergency stop. The brake is integral to the motor, not a field-add-on, so the overall length (212.5 mm) already includes it.
Thermal limits and mechanical constraints
Continuous stall torque is 2.04 N.m at a continuous stall current of 1.5 A — this is the thermal steady-state limit for holding a load at zero speed. The motor is naturally convection-cooled, so any duty cycle above the continuous stall rating requires a duty-cycle analysis to avoid exceeding the 130 °C copper hot-spot temperature. Maximum radial force on the shaft derates with speed: 710 N at 1000 rpm, dropping to 390 N at 6000 rpm. For belt-drive or overhung-load applications, the radial load at the operating speed must stay under this curve — exceeding it shortens bearing life or causes shaft deflection that damages the encoder. The maximum mechanical speed is 8000 rpm, but the motor's nominal speed on three-phase is only 3000–3600 rpm — the extra headroom allows field-weakening operation above base speed for applications like spindle drives that need a constant-power speed range.
