A new high torque permanent magnet brake, model PMB-06 is now available from Ogura. The new model has a smaller diameter than the size 07, but can achieve almost twice the torque of the size 7 by adding only 1/16th of an inch of overall length.The brake comes standard with an armature/hub and 24v coil, but can be modified to a customer’s specification.The new brake’s higher torque, but smaller size makes it well suited for medical and other portable applications where size and weight are critical. The brake joins the other six models of PMB ranging in torque from 0.3 to 22 lb ft. All models come standard with zero backlash which is ideal for servo and high precision holding applications.Besides size and torque, another advantage of permanent magnet brakes over other styles of holding brakes is that permanent magnets can apply a controlled stop, if needed.
