Product details

The BMI0703P37A: Peak stall torque sits at 8.6 N·m across the 208…480 V supply range, while continuous stall torque is 3.4 N·m – a roughly 2.5:1 overload margin for short-duration moves. The IP65 enclosure makes it suited for washdown environments; only the connector and shaft seal need attention during installation.

Torque is voltage-dependent: at 400 V three-phase the motor delivers 2.7 N·m nominal, at 208 V the nominal drops to 2.9 N·m, and at 480 V it is 2.3 N·m – the peak stall torque (8.6 N·m) is the same on any of these supplies, so the voltage choice affects steady-state torque but not the short-term peak. Nominal speed also shifts with line voltage: 3300 rpm at 400 V, 1600 rpm at 208 V, 3900 rpm at 480 V. Ensure your drive's DC bus and motor matching profile accounts for this spread. Feedback is an absolute multiturn SinCos Hiperface – no homing routine needed on power-up, but the drive must support the Hiperface protocol (typically Bosch Rexroth IndraDrive or compatible third-party controllers with the right interface card). Integrated EMC filter means one less component to size and mount in the cabinet, simplifying the CE/EMC compliance path for the overall drive system.

Frequently asked questions

What phase configuration does this motor use?

It is a three-phase motor, designed for 208…480 VAC three-phase supplies.

What is the shaft length of BMI0703P37A?

The shaft length is 30 mm (1.2 in), with a keyed shaft end and 14 mm diameter.

What feedback type does it have?

Absolute multiturn SinCos Hiperface – no homing required after power cycle, but the drive must support the Hiperface protocol.
