Designed, engineered, precision, and durability, Permanent Magnet Brakes are ideal for both motor and non-motor applications. It excel in particular by their compact dimensions and their comparatively low weight. Furthermore, due to their design principle permanent magnet brakes are free of backlash and wear. Permanent magnet brakes are thus ideally suited for applications in medical engineering and servomotor applications, e.g. in handling technology and robotics.
A magnet housing contains an electromagnet coil and powerful rare-earth neodymium permanent magnets. Without power, the permanent magnets create a magnetic field which deflects a flat spring and pulls an armature into the magnet’s surface. The metal on metal contact creates a brake torque. Since the armature is connected to the hub with a riveted connection, the shaft is locked with zero backlash.
When the electromagnet is powered with DC voltage an electromagnetic force is created which opposes and negates the force created by the permanent magnets. In the absence of a magnetic circuit, the flat spring pulls the armature back to the hub. With a small air gap between the magnet and the armature the shaft is free to rotate.
Permanent Magnet Brake advantages include:
·Zero backlash
·small size
·high torque
·no residual torque when running without slip separation
·low noise
·Can run at high RPM
·Easy, mounting
·long life cycle
