The Electro Shear motor brake is simply the best performing, most reliable brake from anyone, anywhere. Electro Shear brakes are spring set; released by 3 phase alternating current. The unit is self contained, totally enclosed and uses advanced composite oil shear friction technology.

Electro Shear Brake - Operation

Electro Shear brakes stop the machine load by the shearing of an oil film between the discs. RESULT - virtually no wear on the disc surfaces. An advanced composite facing material on a steel core is used on alternate discs. The other discs are steel. Multiple springs apply pressure against the disc stack to produce the stopping and holding torque.

3-Phase, alternating current is supplied to the brake coil at the same time it is supplied to the motor. The brake coil releases the spring pressure against the disc stack before the motor winding reaches saturation. RESULT - no overlap, no overheating of motor or brake.

The current to the motor and brake is interrupted at the same time for stopping. AGAIN - no overlap, no overheating of the motor or brake.

 

Electro Shear Motor Brake Features Include:

  • AC Brake - Spring set, electrically released, fail safe brake.
  • Oil Shear Brake - Operates in a bath of hydraulic transmission fluid.
  • Oil Shear Principle - Viscous shearing of the oil between the disc stack absorbs kinetic energy and dissipates heat.
  • Continuous Oil Flow - Dissipates heat, keeps discs cool.
  • Totally Enclosed System - Unit is self contained, impervious to outside contaminants, impervious to coolant and chips from machining.
  • Exceptionally Long Life - Up to six times the life of dry friction brakes*.
  • Simple Installation - Unit mounts to the C-Face of motor. Mounts as one integral unit, no pieces.
  • Precise, Repeatable Stopping - Cycle after cycle, year after year.
  • Inching & Jogging Capabilities - Up to 120 cycles per minute.
  • No Adjustment Necessary - Reduced maintenance costs.
  • Reduced Maintenance Cost

Electro Shear brake technology has proven to last up to six times* longer than competing dry friction brakes. This is due to the continuous oil flow system which prevents overheating of the brake and premature disc wear.

Exceptionally Long Life

The inertia of the machine is stopped by the shearing of an oil film between the friction discs and the steel discs. These discs do not come in contact until 90% of the inertia is absorbed by the shearing of the oil molecules. This leads to exceedingly long disc life. Static and dynamic torque are the same; due to advanced composite disc facings resulting in fast, smooth stops. The oil shear principle allows the Electro Shear brake to have up to six times the life of dry friction brakes*.

Simple Installation

Electro Shear brakes install as a single integral unit allowing for quick installation, inspection and repair. The Electro Shear brake is impervious to coolant, water or dirt which leads to longer friction disc life. The brake mounts on the rear C-flange of a standard NEMA motor. Simply connect the 3 leads to the AC power supply per the service manual directions and the brake is ready for operation
