MagnaShear Electric Release Spring Set Motor Brakes

Designed for Cranes, Loaders, Trippers, and Palletizers
Dynamic Stopping Brakes – Not Just Holding Brakes

Designed with Oil Shear Technology the MagnaShear Motor Brakes typically mount to the back of a brake motor. The newly released coupler brakes are double C-face and mount between the motor and the gear box. They can survive the harsh environments of mining, manufacturing, material handling as well as packaging and food processing with minimal maintenance and no adjustment. The totally enclosed rugged housings keep dirt and moisture out while reducing noise and extracting heat.

“Oil Shear Technology” perfected over 40 years by Force Control Industries provides the brake with up to 10 times the normal life of dry friction units with minimal maintenance and “No Adjustment – Ever”.

Features of a MagnaShear Brake

  • Spring set electrically released - 115 VAC through pulse width modulation for reduced heat and energy cost. Simple transformers are used for alternate voltages. Some DC actuation is available.
  • Direct acting coil eliminates small linkage parts to corrode, hang up, or fail.
  • Multiple disc design for high thermal capacity and low rotating inertia
  • Oil Shear Technology for smooth cushioned stops, minimal wear, no adjustment required, superior heat dissipation and consistent accurate stopping
  • Heavy duty totally enclosed sealed housing for protection in severe dusty, dirty, or wet applications.
  • Quick mount clamped split quill for superior 360º shaft connection minimizing key and keyway problems.
  • Optional wash-down and marine duty designs
  • Custom flange designs for IEC, reducer mounting, or old crane retrofits.
  • Manual release, optional release indicator switch, heater, encoder shaft,
  • Quick mount design installs in one piece. No assembling parts on the motor, small parts to drop, covers to remove for adjustment.

Options and Accessories

  • Manual Release – Designed to allow manual release of the brake when power is off. This allows movement of the machine for maintenance purposes while the power is locked out. The MSB4 and MSB6 have two levers on either side. Both must be turned to fully release the brake. The larger brakes have one large handle on the back.
  • Manual Release Indicator – indicates that the brake has been manually released
  • Wear Indicator Sensor – Indicates when the brake has reached maximum friction disc wear
  • Stub shaft – shaft extended out the back of the brake for  encoder mounting
  • Splined Quill – splined quill for connecting to special splined motor or reducer shaft.
  • Voltage Step down Transformers – required if brake control power is not 115 VAC. Many voltages can be used such as 240, 480, 390, 575, and DC.
  • Marine Duty – Similar to washdown this option is for use on boats, barges offshore rigs, or waterfront loading facilities and ports exposed to fresh or salt water.
  • All of the items  included in the washdown option are included as well as bio degradable fluid.
  • Washdown - All units an be furnished with food grade fluid USDA-H2 for applications where standard fluid may be objectionable. This could be in food processing, or around water.

MagnaShear Brake Typical Applications

Manual Releasemanualrelease – Designed to allow manual release of the brake when power is off. This allows movement of the machine for maintenance purposes while the power is locked out.

 

Manual Release IndicatorMagnaShear Release Indicator – indicates that the brake has been manually released. This is used as a safety precaution to indicate when the brake is no longer holding the load.

Oil Shear Technology - When Reliability is Important

Splined QuillMagnaShear Splined Quill – Especially when doing a retrofit on a crane a splined shaft is often used and requires a splined quill. Force Control Industries can make splined quills with a drawing or by making a mold of the existing spline.

 

Stub shaftMagnaShear Stub Shaft – There are times when an encoder is required especially with VFD drives. The optional shaft extension out the back of the brake is ideal for mounting an encoder.

Voltage Step down TransformersMagnaShear Voltage Step Down Transformer – required if brake control power is not 115 VAC. Many voltages can be used such as 240, 480, 390, 575, and DC.

 

Marine DutyMarine Duty – Similar to wash-down this option is for use on boats, barges offshore rigs, or waterfront loading facilities and ports exposed to fresh or salt water.
