Stepper motors for automation sector

B&R has launched five new 86mm flange stepper motors for the automation sector, with holding torque values ranging from 4.0 to 13.6Nm.

The design and control are said to enable high precision positioning without an encoder system. According to B&R, the 80MPH series stepper motors with an 86mm flange and the 56mm 80MPD series motors are among the most powerful motors currently available on the market with regard to holding torque and length. Equipped with an aluminium housing, the NEMA 34 motors are designed to transport thermal power dissipation with the lowest possible thermal resistance. By doing so, this reduces heating of the motor, which increases the lifespan of the bearings. The close fitting seals protect against oil loss and also prevent dirt particles from penetrating, which ensures that the lubricant is working at full efficiency. This even prevents oil loss when operating at high speeds. The optional IP65 upgrade with built-in clamp for the back of the motor makes wiring easier and permits use in particularly harsh environmental conditions. The dimensioning of the components enables the motors to handle high longitudinal and transverse forces. The stepper motors can be delivered with or without an encoder system. The mechanical robustness of the magnetic encoders ensures trouble-free operation in industrial applications and therefore offers customers maximum reliability.
