Magnetic Disc Brakes

Magnetic Disc Brakes

In Stock

Dimensions

• Metric, foot mounted

Construction

• Fabricated steel mechanism
• All pins ground stainless steel
• Friction linings, high temperature non asbestos

Options

• Service brake self adjusting device(compensates for brake lining wear)
• Limit switches to monitor release / set or wear
• Special materials, tests and finishes as required;
• High integrity requirements such as the nuclear industry

Electrical

• Separate enclosed control units for DC or AC supplies
• Economy circuits available
• Shunt or series magnets available

Applications

• Mechanical handling equipment, cranes, winches,conveyors and mills etc.
• Emergency stop brakes often installed on flange of crane winding drum

Engineering

• Design and selection assistance available

 

Magnetic Actuator

Short stroke DC tractive type with encapsulated coil and screw-off release nut with optional switch. All fabricated steel construction.

• Resin encapsulated coil with Class F insulation
• Optional replaceable coil arrangement for CX range
• 100% continuously rated up to +40°C ambient
• Air gap dust and drip protected by neoprene gaiter
• Terminal box IP55 enclosure

Characteristics

All DC magnets tend to inherently slow response due to build up and decay of the magnetic field. The actual times are dependent on size and vary with excitation voltage, coil temperature and spring loading (torque) and also the magnet stroke which increases as brake linings wear.

Coil Forcing

(Shunt Wound Voltage Operated)

All CU & CX Range brakes are forced open by electric current creating a magnetic field. Brake release and set times are reduced by a separate brake control unit to apply increased power magnetic force during a short preset start period . Control units are enclosed ventilated drip proof IP22 for DC supplies or totally enclosed IP55 with rectifier for 1 or 3 phase AC supplies.
