Product Description:
The 8MSA3L.R0-W0 is a three-phase synchronous motor manufactured by B & R Automation for the 8MS Three Phase Synchronous Motors series. It combines motor size 3 with length code L, allowing it to fit medium-duty axes with limited mounting depth. A self-cooling housing removes heat without external blowers, and the power, feedback, and brake connectors are routed on side B to simplify cable runs. During operation, the unit converts controlled stator currents into accurate shaft motion while a BRX resolver supplies position data to the drive controller.
Under continuous load, the motor delivers 0.99 kW at a rated speed of 4500 rpm and a rated torque of 2.1 Nm; the required electrical input is 2.1 A. The torque constant is 1.04 Nm/A, meaning each ampere of phase current produces just over one newton-meter of torque. During acceleration peaks, the shaft can withstand 10 Nm while the motor draws up to 12.4 A. A stall torque of 2.5 Nm supports static holding tasks, and the relative rated torque is classified as large for its frame. Resolver nonlinearity is ±1 angular minute, while its overall precision is ±10 angular minutes. The resolver uses an analog interface to detect the rotor position without batteries. An integral oil seal protects the front bearing set from contaminants and lubricant loss.
The enclosure carries an ingress protection rating of IP65, guarding internal components against dust and low-pressure water jets encountered on production floors. The motor has a mass of 3.65 kg without a brake, making it suitable for installations where axis weight affects machine dynamics. Its rotor inertia is 1.5 kgcm², balancing quick response with stable speed regulation during changes in commanded velocity. An axial force of up to 200 N may be applied to the shaft during installation without damaging the precision bearings. Loads above this limit should be avoided when fitting couplings, pulleys, or other driven components. Proper alignment during assembly also helps prevent unintended radial loading and supports smooth shaft rotation.
