Multi-voltage speed-torque curves define the application envelope
The SH31401M12F2200 delivers different nominal speeds depending on the supply: 375 rpm on 115 V single-phase, 750 rpm on 230 V single-phase, 1500 rpm on 400 V three-phase, and 1800 rpm on 480 V three-phase. Nominal torque also shifts with voltage — 11 N.m at 115 V single-phase down to 10.4 N.m at 480 V three-phase — so the motor's usable torque at a given line voltage is not a single number but a curve the drive must be tuned to.
Absolute multiturn feedback with holding brake
The absolute multiturn SinCos Hiperface encoder retains position through power cycles without a homing routine — a practical advantage on multi-axis gantries or rotary tables where lost position after a power loss means a recovery move that risks collision. The built-in holding brake delivers 23 N.m holding torque, enough to hold a vertical axis load at rest without the drive maintaining torque at zero speed. The brake is rated for the motor's full mechanical speed of 4000 rpm for emergency stops. Continuous stall torque is 11.1 N.m at 4 A, and the peak stall torque reaches 27 N.m across the 115–480 V three-phase range — the ratio tells you the motor has headroom for acceleration without oversizing the frame.
IP65 motor with natural convection cooling
The motor body carries IP65 per IEC 60034-5, the shaft bushing is IP65, and the housing is IP67 — the shaft bushing seal is the wet-end barrier, so a washdown line with directed spray at the shaft exit is within rating. No external fan means the cooling is entirely by natural convection, so the motor relies on its own surface area and the mounting flange to shed heat. The 140 mm international standard flange with a 130 mm centring collar and 11 mm mounting holes bolts directly to standard gearbox and machine frames without adaptor plates. Maximum radial force at the shaft is 1930 N at 1000 rpm, dropping to 1340 N at 3000 rpm — bearing life is set by the radial load at the operating speed, not the static rating.
