Product details

Speed-torque envelope across supply voltages

The SH31001M12A2100 delivers 2.8 Nm nominal torque at 3000 rpm when fed from 400 V three-phase — the torque drops to 2.52 Nm at 480 V three-phase, and to 2.71 Nm on 230 V single-phase at 1250 rpm. On 115 V single-phase it produces 2.8 Nm at 625 rpm, so the torque constant stays near 1.63 Nm/A at 120 °C copper temperature, but the speed ceiling is set by the available bus voltage.

Feedback and environmental sealing

The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — the multiturn count tracks absolute position over multiple shaft revolutions. This matters for applications where the load position must be known immediately after a power loss, such as pick-and-place or gantry axes. The rotatable right-angled connector lets the cable exit orient to the available clearance in the machine frame.

Mechanical interface and mounting constraints

The motor mounts on an international standard flange with a 100 mm square face and 95 mm centring collar. The 19 mm shaft carries a parallel key (6 mm key width) over a 40 mm shaft length — this is a standard metric keyway that mates with common couplings and pulleys. Maximum radial force at the shaft nose is 900 N at 1000 rpm, derating to 530 N at 5000 rpm; axial force limit is 160 N. No holding brake is fitted — the motor relies on the drive's holding torque or an external brake for vertical-axis loads. The 6.6-inch body length and natural convection cooling mean the motor must be mounted with free air circulation; enclosing it in a tight shroud will raise winding temperature above the 130 °C copper hot limit.
