Electromagnetic Disc Brake | EMB-L-S

Supplier: EMT

The EMB-L-S is a Fail-Safe type, electromagnetic disc brake – meaning the brake is applied when the current to the electromagnet is switched off.

Features

  • Fail-safe braking operation
  • Long wearing brake disc lining
  • High switching frequency
  • Adjustable braking torque
  • No irritating brake noise
  • Manual hand release

The electromagnet is DC operated, which makes it simple, eliminates hum and vibration, gives low energising current and makes it possible to adjust the brake engaging time i.e. the time from when the current is interrupted to when the braking action commences.

The coil of the electromagnet is dimensioned for continuous operation and it is encapsulated in the stator housing with an epoxy compound that makes it insensitive to moisture and vibration.

The braking torque can be adjusted manually and operation of the brake is unaffected by the mounting arrangement.

When the electromagnet of the brake is de-energised, the braking torque is applied by pressure from a series of helical compression springs. The axial movement of the brake disc brings about a double-sided braking action without transmitting any thrust or impacts to motor shaft bearings.

The friction material has high resistance to wear, good thermal conductivity and a uniform coefficient of friction even at high temperatures. The brakes can therefore handle high frequencies of braking without fading. The primary area of application is for electric motors.

For this reason the EMB-L-S brake has been designed to take into consideration the dimensions of standard motors, however in principle their use is suitable for any application where fail-safe brakes are required.

As standard, all EMB-L-S brakes are supplied with a Manual Hand release that allows safe movement of the load even when no power is available.
