Motor frame and feedback — what fits the machine
The SH31002M02F2000: This SH3-series servo motor carries a 100 mm international standard flange (3.9 in) with a 19 mm smooth shaft and a 6 mm keyway — the mounting interface that determines mechanical interchange in a machine build or retrofit. The feedback is an absolute multiturn SinCos Hiperface encoder — it retains position through power cycles without a home sequence, which saves time on machines that power down between shifts or after fault trips.
Torque and speed across supply voltages
Nominal speed ranges from 500 rpm on 115 V single-phase supply up to 2400 rpm on 480 V three-phase — the same motor covers low-speed indexing and high-speed spindle applications depending on the drive and line voltage available. Nominal torque holds between 5.28 N.m and 5.62 N.m across the voltage range, with peak stall torque reaching 18.3 N.m for short-duration acceleration or deceleration events. Continuous power is rated 1100 W, with the motor cooled by natural convection — no external fan or coolant lines, so the thermal budget depends on the mounting surface and ambient air movement in the enclosure.
Brake and sealing — holding the load in place
The integrated holding brake delivers 9 N.m holding torque — enough to keep a vertical-axis load or a conveyor stop position without a separate mechanical lock or brake resistor. IP54 on the shaft bushing without the shaft seal ring, IP65 with the seal ring fitted — choose the seal configuration based on whether the motor sees washdown or just dry dust exposure.
