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.
