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.
