Stepper Motors

B&R is expanding its range of products to include additional high-performance standard devices for the automation industry - with five new 86mm flange stepper motors (NEMA 34) that have holding torque values ranging from 4.0 to 13.6Nm. The design and control enables high-precision and cost-effective positioning without an encoder system. The 80MPH series stepper motors with an 86mm flange as well as the 56mm 80MPD series motors are among the most powerful motors currently available on the market in regard to holding torque and length. Equipped with an aluminium housing, the new NEMA 34 motors are able to transport thermal power dissipation with the lowest possible thermal resistance. This considerably reduces heating of the motor, which increases the lifespan of the bearings. The close-fitting seals not only protect against oil loss, they also generally prevent dirt particles from penetrating, which ensures that the lubricant is working at full efficiency.
