Product Description:

The 8MSA3M.R0-32 is a three-phase synchronous motor manufactured by B & R Automation for the 8MS Three Phase Synchronous Motors series. Designed for industrial automation, it delivers controlled rotation to indexing tables, pick-and-place axes, and similar equipment that demands precise speed regulation. Its size 3 frame fits compact machinery layouts, and the integrated holding brake secures the load when the drive is de-energized, which is useful in vertical or overhung installations and during holding at standstill.

Nominal operation is set at 3000 rpm, giving the axis an inertia match suitable for general-purpose motion tasks. During stops, the built-in brake supplies 4 Nm of static torque to prevent drift. Heat generated by the windings is removed through a self-cooling housing, eliminating the need for forced ventilation. The motor has an overall length code of M. Power and feedback cables exit on side A, which streamlines routing when the stator is mounted with its rear face exposed. Mechanical installation can tolerate an axial push of 200 N on the shaft without disturbing the bearings, and there is no oil seal, so external sealing is required when the shaft faces splash zones.

Position feedback is provided by a resolver that uses the BRX-style carrier to integrate directly with B & R drive modules. The electrical nonlinearity is limited to ±1 angular minute, while overall precision across one mechanical turn is ±10 angular minutes; these values support stable servo loops in high-cycle packaging or material-handling axes. A smooth shaft end eases coupling to backlash-free clamp hubs, helping minimize torsional play in the drivetrain. The medium relative rated torque profile supports balanced acceleration without oversizing the inverter, and the resolver’s temperature stability supports continuous duty during long operating cycles.
