I. Electromagnetic Brake Motors
1.The brake utilizes state-of-the-art AC braking technology and is powered directly by a 380V three-phase supply without any rectifier. It features a wide adjustable braking torque range and two-speed capability, offering the advantages of rapid and reliable braking.
2.The rotor is precisely dynamically balanced and equipped with premium bearings, ensuring quiet operation and minimal vibration.
3.Built-in cooling fans and heat dissipation fins prevent overheating. The standard protection ratings are IP54 for the motor and IP23 for the brake, allowing continuous operation in ambient temperatures up to 40°C. An IP55 rating is also available upon request.
4.The housing can be made of aluminum alloy, offering high impact resistance, corrosion resistance, and an aesthetically pleasing appearance.
II. Axial Flux Motors
1.Ultra-High Power and Torque Density: With the same materials, torque can be increased by 3 to 4 times. Mass-produced models achieve a power density of over 21 kW/kg (up to 25.73 kW/kg) and a torque density of 293 N·m/kg, significantly outperforming traditional radial flux motors.
2.Ultimate Compactness and Lightweight Design: The axial length is reduced by approximately 50%, and the overall weight is decreased by about 50%. This significantly lowers the unsprung mass, optimizing chassis layout and extending driving range.
3.High Efficiency and Low Losses: The coreless structure eliminates iron losses. The high-efficiency zone (>90%) is broad, with system efficiency exceeding 95% and lower temperature rise.
4.Excellent Cooling and Dynamic Response: The planar air-gap structure facilitates oil or air cooling designs and minimizes heat accumulation. The low moment of inertia enables faster start/stop and speed adjustment responses.

Product Uses
1. Lifting & Hoisting Machinery: Essential for electric hoists, winches, and construction elevators where holding the load in a stationary position is critical for safety. The brake prevents the load from falling when the motor stops.
2. Packaging & Printing Machines: Used in vertical packaging machines and printing presses that require precise positioning and frequent start-stop cycles. The rapid braking ensures accurate cutting and sealing locations.
3. Conveyor Systems: Ideal for inclined conveyors. When the motor stops, the electromagnetic brake prevents the materials on the belt from sliding back down due to gravity.
4. Automated Warehousing: Applied in stacker cranes and automated storage/retrieval systems (AS/RS) to ensure precise parking at designated shelf levels.
Product Operate Guide
Mount the motor horizontally or vertically as per the nameplate instructions. Ensure the air gap between the brake disc and the yoke is set correctly (usually 0.3-0.5mm). Wiring: Connect the main motor power to the 3-phase supply. Connect the brake rectifier input to the power supply (often terminals Z1, Z2). Adjustment: If the braking distance is too long, tighten the torque adjustment nuts slightly. Note: Do not run the motor with the brake manually released for long periods.
FAQ
Q1: What is the warranty period for this motor?
A: We offer a standard 12-month warranty from the date of shipment. Extended warranty options are available upon request.
Q2: Why is the brake not engaging immediately?
A: Please check the air gap between the brake disc and the armature. If the gap is too large due to wear, the response time will increase. Adjust the gap to the specified range (0.3-0.5mm).
Q3: Can I use a VFD (Inverter) with this brake motor?
A: Yes, but you must ensure the brake power supply is independent of the VFD output. The brake should be powered directly from the mains or a separate rectifier to ensure it engages correctly when the VFD stops.
Q4: The brake makes a loud noise. What is wrong?
A: Loud noise usually indicates that the brake disc is rubbing against the friction surface due to an incorrect air gap, or the rectifier voltage is unstable. Check the wiring and air gap.
Q5: How do I manually release the brake?
A: Most models have a manual release lever or screw. Turn it to release the pressure, allowing you to move the motor shaft by hand for maintenance. Remember to reset it before operation.
