B&R Industrial Automation: Three-phase synchronous motors
Compact 8JS three-phase synchronous motors, from B&R, are designed for applications requiring quality dynamics and positioning precision.
The permanent magnet, electronically commutated synchronous motors have sinusoidal commutation with an EnDat encoder or resolver as feedback unit. The rotor design ensures minimized moment of inertia and provides the motor with good dynamic properties. The possibility to directly divert lost power generated in the stator to the flange via the housing guarantees efficient regeneration of energy. The self-cooled motors feature an optimized torque ripple and a stall torque between 0.8 and 52.5 Nm.
