P1V-S Stainless Steel Brake Air Motors
  • Integrated spring-loaded disk brake 
  • Reversible

The technology and the size of air motors with integrated running and stationary brake make them ideal applications requiring repeated precise positioning. The motor can also be kept stationary in a specific position, and the stopping time for a rotating weight can be shortened significantly. Another typical application for brake motors is when the output shaft needs to be held in one position when the motor stops delivering torque. The brake can handle more than 1500 braking operations per hour at maximum braking torque.

Service and maintenance

After 20 000 braking operations as a stationary brake or 10 000 braking operations as an operating brake, the brake must be disassembled in order to check for wear.

Warning:

If the number of braking operations is exceeded, the degree of wear might be greater than permitted and the braking effect might be lost.  If this happens, you simply need to replace the worn brake linings.  Tests show that the brake lining needs to be replaced after approx. 90 000 braking cycles.

NOTE!

Brake motors must only ever be supplied with unlubricated air, otherwise there is a risk of oil from the supply air getting into the brake unit, resulting in poor brake performance or no braking effect. 

The integrated brake is a spring-loaded disk brake, which is released at a minimum air pressure of 5 bar. The brake is applied in the absence of pressure. As soon as the control port for the brake is placed under pressure, the piston is pressurized and the spring is compressed. The motor can now start and the torque is passed to the shaft.. The ventilation air from the brake is connected with the atmosphere. In order to brake the motor, the control air to the brake is simply vented. The piston is pushed to the right by the spring, and the axle is jammed between the two brake disks.
