As the trend is towards compact designs, electric drives with high power density are in demand in many applications today. At the same time, however, the integration of electronic assemblies plays an essential role in making drives more intelligent and efficient. The temperature balance in the application is thus becoming more critical and solutions for heat reduction are gaining in importance.
Kendrion has reacted to these requirements and developed the control modules of the "Slim Collection" especially for this purpose. They are offered as PWM modules for servo motors or as rectifiers for asynchronous motors and are suitable for brakes up to approx. 225 W holding or 450 W switching power. For fast and powerful switching on, the full switching voltage can be provided for a limited time, which shortens the opening time. Afterwards, the electronics switch down to a variable value under microcontroller control, resulting in energy savings of up to 75% and heat reduction. Thanks to the use of highly integrated electronic components, the modules also take up significantly less space than conventional solutions.
The complete electronics are housed on a plastic-molded circuit board and can thus be mounted close to the drive or in the terminal box of the motors with just one central screw. In addition, an optimized manufacturing process allows smaller quantities to be produced at low cost.
The advantages can be summed up in a few words: compact design, high power density, simple assembly and favorable price.
Slim Collection AC - overexcition
These types of Slim Collection AC operate as a time controlled rectifier with integrated electronic fast turn-off through voltage detection.
Slim Collection AC - half-wave/bridge
These types of Slim Collection AC operate as a half-wave/bridge rectifier with integrated electronic fast turn-off through voltage detection (depending on type).
Slim Collection DC - DC voltage
The Slim Collection DC operates as a time-controlled PWM amplifier (pulse width modulation).
