Electromagnetic motor brakes are commonly used as compact hoist motor brakes or auxiliary brakes on smaller overhead cranes, wire rope hoists, chain hoists, and positioning drives. They are typically mounted on the motor end (or integrated into the motor design) and provide fast engagement and release. Many are spring-applied and electrically released, so they can function as a fail-safe holding brake for certain duty levels.
These brakes are especially useful when space is limited and a direct motor-mounted solution simplifies installation. They are also common on mechanisms requiring quick response and frequent engagement, such as small trolley drives or auxiliary hoists.
However, motor brakes have limits: torque capacity and heat dissipation may not match heavy-duty hoisting needs on large cranes. For higher-risk lifting, the crane may require a larger dedicated brake on the gearbox or drum shaft, or a secondary brake for redundancy. Always match the motor brake rating to the actual reflected torque and duty cycle.
