Motor specs and what they mean for your axis
The SH30702M02F2100 is a three-phase servo motor from the SH3 family, delivering 640 W continuous power with a nominal torque range of 17.97 to 19.5 lbf.in depending on the supply voltage (115 V single-phase through 480 V three-phase). That torque spread means the motor's output is voltage-dependent — if you're running it on a 480 V three-phase line, expect 17.97 lbf.in nominal; on 115 V single-phase, you get the full 19.5 lbf.in. Peak stall torque hits 67.3 lbf.in (7.6 N.m) across the 115 to 480 V three-phase range, so it can handle short-duration overloads for acceleration or reversing without dropping out of sync. The holding brake delivers 26.6 lbf.in (3 N.m) static torque — enough to hold a vertical axis load at rest without power to the motor windings, which is the whole point of a brake motor on a pick-and-place or gantry.
Encoder and feedback — absolute multiturn Hiperface
The encoder is an absolute multiturn SinCos Hiperface type, which means it tracks position through multiple shaft revolutions even after a power cycle — no homing routine needed on startup. This is the feedback you want on a machine that must resume operation from a known position after a power loss or emergency stop. The SinCos analog track gives high-resolution interpolation for smooth low-speed control, while the Hiperface protocol carries the absolute position data over a single cable pair — keeps the cable count down on a moving axis.
Mounting, cooling, and environmental fit
The motor mounts on an international standard flange with a 70 mm (2.8 in) square pattern and a 60 mm centring collar — drops into the same bolt circle as many common servo frames, so a retrofit into an existing machine bed is straightforward if the old motor used a 60 mm pilot. Cooling is by natural convection — no fan, so no forced-air noise or filter maintenance, but the thermal budget is limited to the housing surface area. The continuous stall current is 1.5 A, and the stator resistance is 16.4 ohm, so the I²R heat at stall is about 37 W — the housing sheds that without a blower in a clean ambient. IP65 on both the motor body and the shaft bushing means it handles washdown spray and airborne dust — suitable for food processing, packaging, or any line where you hose down the machine between batches.
No official successor or cross-reference is recorded — this is the current build, not a legacy part.
