Birkerød, Denmark - JVL A/S, one of the world leaders in the field of integrated servo- and stepper-motors introduce a new compact electro-magnetic brake with superior torque performance compared to other NEMA17 brakes on the market. The MAB17 brake is a totally new design based on years of experience and customer feedback.

 

The brake is used when it is desired to hold the motor shaft fixed at power-off, typically when the motor is used in a vertical linear application. When 24 VDC is connected, the brake is deactivated and the motor can turn freely.

 

The electro-magnetic brake is designed to be mounted on step- and servo-motors with NEMA17 flange 42x42mm. The brake can be mounted directly on any brand of stepper motor that follows the NEMA17 standard like JVL stepper motor MST17x but also JVL integrated stepper motors MIS171, MIS173 and MIS176. Output shaft and (hollow) Input shaft are available in 5, 6.35 or 8 mm but others can be produced to order.

 

A high quality 24 VDC electro-magnetic spring brake is mounted inside the housing. The brakes use shaft-hub-connection to the brake disc which allows for axial play ensuring that the motor bearings are not overloaded e.g. due to temperature changes.

 

0.5 Nm holding torque is standard but 0.6…0.7 Nm special selected brakes are available. High quality shaft collar ring with screw is used to tighten the brake onto the motor shaft.

 

Key features:

• Very high torque holding brake 0.5 Nm
• High quality spring brake which absorbs axial play in motor
• IP65 option available for both shaft and housing
• 12VDc or other windings available
• Low current consumption
• 5, 6.35 and 8 mm in- and output shaft standard
• M8 connector standard. Free wire or cable also available on request
• Stock available for instant delivery

Front mounted hollow shaft brake 6.35, 8 or 10 mm is also available for motors with double shaft or lead/ball screw.

 

All standard brakes are equipped with M8 4 pin male connector for 24 VDC control voltage.
