Advantages of classic synchronous motors
A variety of individual drive solutions and special designs as per customer request are daily business for ROTEK . They are all based on the synchronous motors of the ROTEK modular system. All motors have a diameter of 65 mm and the same external design. This means they can be combined with any component of this modular system.
Robase motors are the name of our classic synchronous motors. They combine all the advantages of synchronous technology. Due to their design, synchronous motors have no losses in the permanent-magnet, conductorless rotor. Therefore, they have a higher efficiency and lower energy consumption than asynchronous motors of the same performance – and with a smaller installation space.
They provide constant speeds regardless of the load and allow starts and stops within fractions of a second. In the de-energized state, the rotor magnets hold on to the pronounced stator teeth. A mechanical brake, which is subject to wear and costs installation space, is not necessary. Robase motors are available with four poles (1500 1/min) or six poles (1000 1/min).
The proven technology and its advantages are predestined for certain applications. Synchronous motors are mainly used where high accuracy, synchronicity in the motion sequence of different axes, and a constant drive speed are required, e.g. in printing, textile machines, or conveyor systems.
Due to their compact design, they are a good solution in confined spaces within machines and plants. In positioning operation, their constant speed, independent of frequency and load, and their dynamic response and braking behavior are particularly important. On top of this, they have a long service life, they run reliably in pellet heaters and actuators, and they can save a brake in many applications. ROTEK has sold over a million of them to date.
