Product details

Mechanical and integration notes

The BMI0703P12A: Shaft is keyed — 0.6 in (14 mm) diameter, 1.2 in (30 mm) long, with a 0.2 in (5 mm) keyway. Motor mounts to an international standard flange with a 2.8 in (70 mm) flange size and 2.4 in (60 mm) centring collar. IP54 at the shaft, IP65 on the housing — fine for wash-down or dusty environments with care at the seal. The holding brake is omitted, so external braking is required if you need holding torque. Cooling is by natural convection; no fan for forced air, which means derate if mounted in a confined space with restricted airflow.

Frequently asked questions

What is BMI0703P12A's phase and length?

It is a three-phase motor, 11.8 in (300 mm) overall length (excludes shaft extension).

What feedback type does the motor use?

Absolute multiturn SinCos Hiperface — a specific protocol common with Bosch Rexroth drives. Make sure your drive supports Hiperface before ordering.
