Precision as passion.

Precima Magnettechnik GmbH was founded in 1981 and is today established as an independent, medium-sized, innovative family-owned brake manufacturer.

With our staff of more than 200 employees, we develop and produce a wide range of electro-magnetic operated brakes and clutches for all kinds of applications in machines and other industries. Our standard range of products covers a performance scope of braking torques between 0.5 and 1,600 Nm.

Thanks to our advanced CNC machining technology and well-organized assembly lines we produce more than 650,000 units per year. The high rate of self-manufactured parts provides us with maximum flexibility and allows for short response times. Our own highly qualified and experienced engineering and development departments are specialized in producing customized brake solutions on a very high technical and economic standard.

Spring-applied electromagnetic brakes

The PRECIMA spring-loaded brakes are electromagnetically actuated single disc brakes with two friction surfaces.

The PRECIMA spring-loaded brakes are electromagnetically actuated single disc brakes with two friction surfaces. The braking power is applied by means of pressure springs. The...

PRECIMA Clutches

Electromagnetic clutches

Precima electro-magnetic clutches and load currently operated brakes were specifically developed for the requirements of advanced machine and apparatus construction.

Thanks to high-quality standards in development, material selection, and manufacturing they meet all demands of modern motive power engineering.

PRECIMA Rectifier

Half-wave and bridge rectifiers

  • PMB = Bridge Rectifier
  • PME = Half-Wave Rectifier
  • PMEA = Half-Wave Rectifier with protection against overvoltage
  • PMG = Fast Response Rectifier

These compact modules have been specially designed to be fitted into the terminal boxes of electric motors.

The PME half-wave rectifier which halves the supply voltage is the most cost-effective.

The PMB full-wave bridge rectifier produces a smooth DC voltage (95% of the supply voltage).

Both rectifiers are available for switching on AC or DC side.

Varistors in the input and output protect the rectifiers from surge voltage.

The PMG fast excitation rectifiers are recommended whenever short release times or low dissipation are required. It combines the benefits of the half-wave and bridge rectifiers.

We can't find products matching the selection.
