Electric brake motors are drives with a built-in electromagnetic brake that stops the shaft within a fraction of a second after the power is cut. At Stojan you will find three-phase and single-phase brake motors in a wide power range — reconditioned and tested with a warranty, as well as new units from manufacturers. Most are dispatched within 24 hours from our warehouse in Poland.
How does the brake in an electric motor work?
The standard brake is a spring-applied holding brake (fail-safe). When the motor is energised, the electromagnet pulls in the armature disc and releases the brake — the shaft rotates freely. When the power fails, the springs press the friction linings against the brake disc and immediately lock the shaft. This means the drive holds the load even during a power failure — essential for the safety of lifting equipment.
Where are brake motors used?
- Winches and hoists — the brake holds the load in place after stopping and during a power cut.
- Gates and barriers — precise stopping in the end position.
- Conveyors and feeders — instant stop without belt overrun, important for dosing and positioning.
- Machine tools and packaging machines — stopping the cycle in an exact position.
- Overhead cranes and lifts — safety for the operator and the load.
How to choose a brake motor
In addition to the standard parameters (power in kW, speed, 230 V / 400 V supply, B3/B5/B14 mounting arrangement), pay attention to the braking torque — it must be matched to the inertia of the driven machine. For lifting drives, the brake torque should exceed the load torque with a safety margin. Other important factors are the brake coil voltage, a manual release option (release lever) and the IP protection rating.
Need a drive that combines speed reduction with a brake? See our brake gearmotors — a worm gearbox is also self-locking. Looking for two speeds? See our two-speed motors. Have a question about a specific model? Call +48 500 385 112.
