What Is an AC Brake Motor?
AC brake motors integrate an electromagnetic power-off brake that engages automatically when power is removed. This fail-safe design ensures quick stopping and strong holding torque, making them ideal for machines that lift, index, or frequently start and stop.
Types & Drive Options
Fixed-Speed Brake Motors
- Single-phase 220V (capacitor-start) – simple wiring and stable fixed speed.
- Three-phase 220V / 380V – recommended with a VFD for soft start/stop and smoother operation.
Variable-Speed Brake Motors
- Work with a speed controller for adjustable RPM, smooth acceleration/deceleration, and consistent torque.
Power & Size Range
- Power: 6W – 750W
- Mounting sizes: 60×60 mm to 120×120 mm compact square frames
Gearbox Options & Ratios
- Parallel-shaft gearboxes – compact inline drives
- Right-angle reducers – hollow-shaft or solid-shaft options for space-saving layouts
- NMRV worm gear units – smooth, high-reduction drives for very low-speed output
- Gear ratios: 3:1 up to 500:1
Typical Applications
Conveyors, packaging and labeling lines, indexing tables, small hoists, automated doors, and positioning systems that require safe braking and reliable load holding after power loss.
Key Benefits
- Fail-safe braking with strong holding torque
- Flexible control options: VFD or speed controller
- Compact footprints and multiple gearbox choices
- Wide ratio range for precise low-speed performance
