Rotek customarily offers Romotion with integrated control electronics. However, complex control options are not necessary for an application where a solid standard solution will also suffice. Often, customers only require a relatively simple speed control and change of rotation direction. In such cases, Rotek offers its customers low-cost control electronics developed by its partner company ebeTEC in Austria for Romotion.
The motor controller for 24 V DC works without sensors and upgrades the “back EMF” for commutation. As a result, factory sensors are not required in the motor, making the drive inexpensive. The speed setpoint value is determined by the voltage input range between 0 and 10 V. In addition, there is a 10 V digital input for the direction of rotation. Finally, there is an open collector output for speed monitoring with 2 pulses per revolution. A power output up to 100W / 4A is possible.
Significantly less space required
The control electronics are cast and sealed directly in the motor body in a “hot melt” process. This is integrated in the connecting cable of the motors. No additional slot, installation space, housing or control cabinet is needed which significantly reduces the space and wiring work required and keeps our product flexible and inexpensive. It also has optimal protection against environmental influences.
Simple drive-tasks e.g. for ventilators, pumps or the drum-turning of rotation heat-exchangers
Unfortunately, the chip for our low-cost electronics L44 has not been available for some time. We have reserved the now only small remaining quantities for existing customers. The L44 will probably not be available again until the third quarter of 2023. However, if required, we can offer another low-cost alternative in the meantime.
