by Canadian Packaging Staff

The synchronous motor product family from B&R Industrial Automation has grown with the release of its compact 8JS three-phase synchronous motors.

The universal 8JS motor series features high performance with a compact size. The permanent magnet, electronically commutated synchronous motors are designed for applications requiring excellent dynamics and positioning precision.

Featuring a sinusoidal commutation with an EnDat encoder or resolver as feedback unit, the 8JS motors offer an exceptionally effective rotor design that ensures minimized moment of inertia and provides the motor with the best possible dynamic properties.

The motor also offers the ability to directly divert lost power generated in the stator to the flange via the housing to guarantee an efficient regeneration of energy. An optimized torque ripple and a stall torque between 0.8 and 52.5 Nm fulfills all requirements for sophisticated motor solutions.

The self-cooled 8JS motors are available in six different sizes and offer the user the most freedom possible for application tasks where space is an issue. Easy access to mounting screws for fastening the flange makes it possible to install motors easily without negatively affecting other parts of the system. 8JS series motors have a high overload capability and an exceptionally long lifespan.
