Motor specs and drive pairing constraints
The SH30703P0AF3000 is a three-phase servo motor from the SH3 series, delivering 1330 W continuous power at 400 V or 480 V three-phase supply (830 W at 230 V single phase). Nominal speed ranges from 3000 rpm on 230 V single phase up to 7200 rpm on 480 V three phase — the speed-torque curve shifts with the supply voltage, so the drive's DC bus voltage must match the target speed band. Nominal torque is 24.8 lbf.in (2.8 N.m) at 230 V single phase, dropping to 18.6 lbf.in (2.1 N.m) at 400/480 V three phase — the lower torque at higher voltage reflects the motor's constant-power region above base speed. The absolute single-turn Hiperface DSL encoder provides position feedback over a digital serial link, eliminating analog encoder cable noise issues — the drive must support Hiperface DSL protocol; check compatibility with your Lexium or third-party drive.
Brake, inertia, and vertical-axis duty
The integrated holding brake delivers 26.6 lbf.in (3 N.m) holding torque — sufficient to hold a vertical load at standstill without the drive holding the position electrically. Brake pull-in power is 7 W, so the brake coil draw is low enough for a standard 24 VDC control supply; the brake release time is typically in the tens of milliseconds — budget this into the sequence when the axis starts moving after a stop.
The sizing reference SH30703P groups the motor family; confirm the encoder option and shaft configuration match your application before committing. Maximum RMS current is 17 A — size the drive and cable for at least this peak draw; the continuous stall current is 4.1 A, so the drive's continuous rating should cover the lower figure while the peak rating handles acceleration transients.
Environmental sealing and mechanical integration
The motor body carries IP65 protection — suitable for washdown and dusty environments. The shaft bushing without the shaft seal ring drops to IP54; if the application sees direct spray on the shaft exit, specify the optional shaft seal. Motor flange size is 2.8 in (70 mm) with a centring collar diameter of 2.4 in (60 mm) and a centring collar depth of 0.10 in (2.5 mm) — mounts to the standard IEC 70 mm flange pattern. Shaft diameter is 0.6 in (14 mm) with a smooth shaft — the smooth shaft means the coupling must be clamped or keyed; no keyway is provided, so use a shaft-locking coupling or add a keyway during installation. Electrical connection uses a rotatable right-angled connector and a quick-lock straight connector — the connector orientation can be adjusted after mounting, simplifying cable routing in tight panels.
