Product details

Power and speed across supply configurations

The SH31401M01A2000 delivers 1700 W continuous power, but the nominal torque and speed depend on the supply voltage and phase configuration you feed it. At 115 V single-phase, expect 11 N.m at 375 rpm; at 230 V single-phase, 10.95 N.m at 750 rpm; at 400 V three-phase, 10.6 N.m at 1500 rpm; and at 480 V three-phase, 10.4 N.m at 1800 rpm. The three-phase winding is the native configuration — the single-phase figures reflect derated operation. If your line runs 400 V three-phase, you get the full 1670 W nominal output power at 1500 rpm.

Encoder feedback and environmental sealing

Absolute single-turn SinCos Hiperface encoder means the drive knows the rotor position at power-up — no homing sequence needed on each cycle. This matters for applications where the machine must resume position immediately after a power loss or E-stop. IP54 as standard with the shaft bushing without seal ring; upgrade to IP65 by fitting the shaft seal ring, per IEC 60034-5. The IP65 variant withstands washdown environments — food processing or packaging lines where hose-down cleaning is routine. Natural convection cooling — no fan, so no additional noise or maintenance item. The thermal limit is set by the copper hot-spot temperature of 130 °C.

Torque, inertia, and mechanical limits

Maximum mechanical speed is 4000 rpm, giving headroom above the 1500–1800 rpm nominal range for rapid-traverse moves. Maximum radial force at the shaft is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm — plan bearing life around your actual speed profile.

Mounting dimensions and flange pattern

International standard flange with 140 mm flange size, 130 mm centring collar diameter, and 11 mm mounting holes. Overall length is 217.5 mm, shaft diameter 24 mm with a 50 mm smooth shaft — no keyway, so the coupling or pulley must clamp onto the smooth diameter. Smooth shaft end and 8 mm key width are absent here — this variant is specified for applications where a keyed connection is not required, such as direct coupling via a clamping hub.

Frequently asked questions

What is SH31401M01A2000's listed phase configuration?

The motor is wound for three-phase operation, though it can run on single-phase supplies with derated torque and speed as shown in the spec table.

What encoder type does SH31401M01A2000 use?

Absolute single-turn SinCos Hiperface encoder. This provides absolute position feedback within one revolution without requiring a homing routine at power-up.
