SOLBRAKE DC Injection Brakes

Dynamic Brakes for AC Motors 4-315KW, 220-690V

The SOLBRAKE is the ultimate replacement for the old electrical braking systems such as Reversing (which may result in reversing the motor rotation) or Regenerative braking (which requires resistors to absorb the energy).

The SOLBRAKE will help to bring your equipment inline with the safety requirements of PUWER 98.

Solid State Motor Brakes provide fast, smooth, frictionless braking of squirrel cage motors by injecting controlled DC current into the motor windings, after mains contactor has opened. This induces a stationary magnetic field which exerts a braking torque on the rotor.

The SOLBRAKE can be used with mechanical brakes to softly bring the motor speed to zero before operating a mechanical brake.

Advantages at a Glance

• Reduced stopping time - To increase production rate in machine tools and high inertia loads
• Reduced stopping time - To increase safety in hazardous machines
• Soft, smooth stopping, preventing wear and tear of mechanical parts
• Adjustable braking torque, matching load size and required stop time
• Auto stop, reducing motor heating
• Maintenance free, highly reliable operation
• Easy installation in electrical switchgear

Typical Applications

• Machine tools
• Circular saws
• Safety brakes
• Large flywheel applications
• Fast stopping of high inertia loads

EzBk Easy Braking IP54 Enclosure 400VAC

DC Injection Brakes for AC Motors 0.75-30KW

The EzBk is a fully integrated solution to ensure your machine is compliant with the PUWER 98 Safety regulations. We use our Solbrake DC Injection Brake and install it in an IP54 enclosure with all the necessary control logic, with a Start and Mushroom Latched Stop button on the front.

Inside the EzBk is everything you need for a DOL Start and DC Injection Brake Stop. All required fusing and thermal overload protection for your Motor is included. All you need to do is remove your existing control box and replace it with an EzBk, it just requires 3 Phase Input and 3 Phase output to your Motor.

The SOLBRAKE will help to bring your equipment inline with the safety requirements of PUWER 98.

We can also build machine specific panels, so if you have a multiple motor machine which requires DC Braking, please contact us for further details.
