Bremerhaven, October 2022 - With its Romotion BLDC motors, Bremerhaven-based small motor manufacturer Rotek offers a series that is suitable for a wide range of intralogistics requirements thanks to its intelligent electronics. The possible applications range from relatively simple conveyor belt drives with analogue speed specification to CAN bus-capable drives for driverless small load transport systems.
The Romotion can be customised mechanically, electronically and in terms of software to optimally meet the respective requirements. If crates with different loads are to be positioned at maximum cycle rates, the software can be programmed so that the stopping point is approached without time-consuming readjustment. The overall dynamics are determined when the containers are accelerated at maximum flow. This is used to calculate the optimum braking time depending on the load while travelling at maximum speed. After active braking, the drive switches to stepper motor mode for the last 1-2 steps and moves synchronously to the stopping point with high overexcitation. An output for a braking resistor is provided as standard on the control electronics.
If a transport container needs to be permanently levelled, Rotek offers the option of installing an inclination sensor directly in the Romotion and connecting it to the electronics. The drive can be calibrated during commissioning. This saves the system manufacturer additional costs for mounting and wiring the sensor. In addition, the direct connection of the sensor to the motor electronics enables fast control and therefore a particularly smooth drive.
The Romotion drives cover a power range from 80 to 200 W and are available for nominal voltages of 24 and 48 V. In the sensorless standard version, they can be operated between 400 and 4000 rpm. In sensor operation, the speed range can be extended considerably.
The power supply for power and logic can be disconnected for safety shutdown. This means that the drive remains permanently ready for communication, but cannot start. On request, the Romotion is also available with the drive-integrated safety function STO (safe torque cut-off). This ensures that a switched-off motor can no longer safely generate torque. In accordance with stop category 0 of EN 60204, the power supply is interrupted immediately and the drive coasts to a torque-free stop.
In the download area of the website, Rotek offers the latest version of the MotorManager parameterisation software with an extended range of functions. In addition to standard settings such as speed ranges, ramps and current limits, users can now also customise the PID controller according to their requirements. The drive can be operated on a control panel for easy commissioning.
With the same external design as the other Rotek motors, the Romotion BLDC motor fits all components from the Rotek modular system. In addition to the proven planetary gearboxes, Rotek now also offers the motor with worm gearboxes. A combination with robust parallel shaft gearboxes is also possible.

About Rotek:
Rotek GmbH & Co. KG was founded in 2000 and took over the business area of Hasselbach & Kausch Elektrokleinmotoren GmbH in Bremerhaven, which was founded on 10 July 1984 by Paul Hasselbach and Hans-Werner Kausch. The company is managed by three partners. Dipl.-Ök. Rolf Treusch is responsible for the commercial area, Dipl.-Ing. Klaus Treusch is responsible for design, production and quality assurance and Prof. Dipl.-Ing. Wilfried Treusch is head of development.
The family-owned company specialises in the production of geared motors in small and medium-sized series. Precision motors from Rotek are used in equipment and apparatus engineering, mechanical engineering, heating technology and intralogistics. The Bremerhaven-based motor manufacturer has developed into a global specialist for customised drive solutions with a long service life. In February 2010, the company won the "preis umwelt unternehmen: nordwest" award for its Rosync energy-saving motor. In 2016, the intelligent drives in the Romotion series were honoured with the bronze medal at the Schütting Prize, the most important innovation competition in the state of Bremen.
