AC Brake Motor

AC Brake Motors are offered in three configurations to meet different automation and material-handling requirements. The single-phase 220 V variable-speed type works with a controller for stepless speed regulation, while the single-phase 220 V fixed-speed capacitor-start version provides stable, single-speed operation. For higher-power or inverter-driven systems, three-phase brake motors (220/380 V) deliver efficient and adjustable speed control. All models incorporate fail-safe electromagnetic braking for secure load holding, precise stopping, and dependable power-off performance in conveyors, packaging lines, hoists, and lifting equipment.

What Is an AC Brake Motor?

AC Brake Motors feature an electromagnetic Power-Off Brake (E-Brake) that automatically engages when power is lost. This fail-safe system ensures quick stopping and strong holding torque, making them ideal for machinery requiring precise control in lifting, indexing, positioning, and frequent start-stop cycles.

Types & Drive Options

Single-Phase Fixed-Speed Brake Motors (220 V, Capacitor-Start)

Designed for stable, single-speed operation without the need for a VFD. They offer simple wiring and easy installation for general-purpose automation equipment.

Single-Phase Variable-Speed Brake Motors (220 V)

Compatible with a speed controller for adjustable RPM. These motors deliver smooth acceleration and deceleration with consistent low-speed torque output.

Three-Phase Brake Motors (220 V / 380 V)

Used with a VFD (Variable Frequency Drive) for wide-range speed control, soft start/stop functionality, and higher continuous torque for demanding industrial applications.

Power & Size Range

  • Power Output: 6 W to 750 W
  • Mounting Sizes: 60×60 mm to 120×120 mm square frames

Gearbox Options & Ratios

Available gearbox configurations to support low-speed, high-precision applications:

  • Parallel-shaft gearboxes: Compact inline design for efficient use of space.
  • Right-angle reducers: Offered in hollow-shaft or solid-shaft models for flexible layouts.
  • NMRV worm gear units: Smooth, high-reduction output for ultra-low-speed applications.
  • Gear Ratios: From 3:1 up to 500:1.

Typical Applications

  • Conveyors
  • Packaging and labeling lines
  • Indexing tables
  • Small hoists
  • Automated doors
  • Positioning systems

Key Benefits

  • Safety First: Fail-safe braking with high holding torque.
  • Flexible Control: Works with VFDs or speed controllers.
  • Modular & Compact: Multiple mounting sizes and gearbox combinations.
  • Precision Performance: Wide ratio range for low-speed, high-accuracy movement.
