Electric Motor Brakes

Dings spring-set disc brakes that stop and hold the load when the power goes off

A motor brake is the last line of defence on a hoist, crane, conveyor or door: when power is cut, intentionally or not, the brake has to set and hold. Gordon Russell is an authorized distributor of Dings motor brakes, and we repair and rebuild them in our power transmission shop.

Dings has built electric motor brakes in Milwaukee, Wisconsin since the 1950s. Every Dings brake is spring-set and electrically released: when the motor is powered, an electromagnet pulls the pressure plate back and the brake runs free; when power is removed, springs clamp the friction discs and stop the load. The direct-acting design has one moving part and no linkages to wear out or break, so it outlasts solenoid-actuated brakes.

Brake Repair, Rebuilds & Drive Packages

Keep the brake working as hard as the motor

A worn brake rarely fails all at once: friction discs wear, the air gap opens up, and stopping distance creeps out until the load drifts. We repair and rebuild Dings brakes, and supply brakes already matched to the motors and gearboxes we sell.

What We Do:

  • Repair and rebuild: Dings brakes inspected, rebuilt with new friction discs, springs, coils and seals, and adjusted to the correct air gap and torque.
  • Replacement parts: friction discs, coils and rebuild parts for Dings brakes.
  • Brake motor packages: brakes supplied with TECO-Westinghouse, WorldWide Electric and Bonfiglioli motors and with our gearboxes and couplings.
  • Replacements: Dings brakes sized to replace worn or obsolete brakes from other makes on standard NEMA C-face motors.

Common Applications:

  • Hoist, crane and conveyor maintenance
  • Adding brakes to new and replacement motors
  • New brake motor drive packages

FAQ

What is a spring-set, electrically released brake?
It is a fail-safe brake: springs hold the brake on, and an electromagnet releases it when the motor is powered. When power is switched off or lost, the springs clamp the friction discs and stop and hold the load. Every Dings motor brake works this way.
What does direct acting mean, and why does it matter?
In a Dings direct-acting brake the magnet acts directly on the pressure plate, with one moving part and no levers or linkages. There is less to wear, adjust or break than in a solenoid-actuated brake, so the brake lasts longer and needs less maintenance.
Which Dings brake fits my motor?
Start with the motor NEMA frame: the 40 Series suits fractional HP motors, the 50 Series 48C, the 60 Series 56C to 145TC, the 70 Series 182TC to 256TC, the 80 Series 284TC to 286TC and the 90 Series 324TC to 405TC. Then choose the torque, enclosure and coil voltage. Send us the motor nameplate and we will select the brake.
How do I size the brake torque?
Brake torque is usually sized at or above the motor full-load torque, which is 5,252 times horsepower divided by rpm in lb-ft, multiplied by a service factor for the application. Hoists, cranes and vertical loads need a higher factor than horizontal conveyors. The Dings Brake Selection Guide in our literature table walks through the calculation, or we can size it for you.
What enclosure do I need?
NEMA 2 dripproof brakes suit clean indoor areas. NEMA 4 and 4X brakes are waterproof and dust-tight for outdoor, washdown and corrosive areas, and a hub seal adds protection. Hazardous location brakes are for Division 1 Class I Groups C and D and Class II Groups E, F and G areas, and naval duty brakes are for shipboard service.
Can a Dings brake replace a brake from another manufacturer?
In most cases, yes. Dings brakes mount to standard NEMA C-face motors, so we can match the frame, torque, enclosure and voltage of your existing brake. Send us the nameplate and a photo of the brake you are replacing.
Do you repair and rebuild Dings brakes?
Yes. We repair and rebuild Dings brakes in our power transmission shop, replacing worn friction discs, springs, coils and seals and setting the air gap and torque before the brake goes back into service.
How often should a motor brake be inspected?
It depends on the duty: check brakes on hoists, cranes and frequently cycled conveyors more often than lightly used brakes. Look for friction disc wear, an air gap outside specification, and slipping or slow setting. The Dings manual for your model lists the wear limits and adjustment procedure.
Can I get a brake for 575 V or a special voltage?
Yes. Dings brakes are available with AC coils in standard single- and three-phase voltages, including 575 V, 60 Hz, and special voltages and DC coils on selected models. Tell us the supply voltage, phase and frequency when you request a quote.
Can you supply the brake with the motor and gearbox?
Yes. We supply electric motors, gearboxes and couplings, so we can deliver a brake motor or a complete drive package with the brake already matched to the motor frame and the load.
