    Contactless Magnetic Electric Brakes

    Image of Product. Front orientation. Brakes. Contactless Magnetic Electric Brakes.
    Create drag to slow or stop the motion of your drive system using magnetic force. Because torque is transmitted by magnetic force without contact, there is no wear, so these brakes give you accurate, repeatable braking. Also known as electric hysteresis brakes, they are often used in tensioning, holding, and stopping applications. The brake engages when the power is on and releases when it is off. The amount of electrical current determines the amount of torque that is applied by the brake. Use these brakes with a current-limiting transformer.

    Noncontact Magnetic Torque Limiters

    Using magnetic force instead of friction to transmit torque, these torque limiters won't wear when they slip. Because there's no wear, they give you accurate, repeatable action. Also known as hysteresis clutches, use them to brake, control tension, and prevent torque overload. They are designed to slip during a torque overload while still transmitting the set torque. For example, you can use them to maintain a constant tension while winding and unwinding wire. All are through-shaft torque limiters, so they regulate torque transmission between an input shaft and a mounted component, such as a pulley, sprocket, or gear. Twist the adjustment ring to set the torque limit, then lock the ring into place with the included set screw.

    Unlike standard AC motors, these motors have an integrated brake that activates after a power loss to hold your equipment in place. They’re often used with conveyors to stop them from moving backwards after a power loss, and with hoists to prevent them from dropping a load. Mount their base to flat surfaces. Rated for continuous duty, these motors can run equipment that never turns off. Their shaft is keyed, and they come with key stock.
    Totally Enclosed Fan-Cooled (TEFC) Motor Enclosure—These motors have a TEFC (totally enclosed fan-cooled) enclosure that protects better than an ODP (open dripproof) enclosure. They aren’t airtight, but they can be used in dirty, dusty, and wet environments. To keep the motor cool, the enclosure has an external fan that blows air over the outside of the motor.

    When these motors lose power, a brake engages to hold your equipment’s position, unlike standard AC motors. They’re often used with conveyors to keep items in place after a power loss, and with hoists to stop them from dropping a load. Mount them from the base or face. Rated for continuous duty, these motors can run equipment that never turns off. Their shaft is keyed, and they come with key stock.
