Advantages of the servo drives over classical drives solenoids
With servo drives, you realize vorbildnahe movements on your investment
The current trend in the model railroad are movements and animations. An increasing role to play servo drives. Servo drives can be found at the model especially in the propulsion of switches, signals, barriers and other functional models of all kinds is a servo drive consists of an electronic control system (servo control), the servo motor and a gearbox. Serve as an engine usually regulated, brushless DC motors or less vector controlled Asynchron-/Synchronmotoren. In the digital model there is an additional digital decoder, which allows to control the digital control electronics. Compared with the traditional magnetic coils drive the servo drive has several advantages: start and end position of the control areas have to be very precisely adjusted, it is-wear and the dynamics of the movement can vorbildnah run slowly and almost silently. Moreover servos offer more power than coil drives, so the model can also be "heavier" moving loads. Current mini servos reach a force of up to 1 kg / cm. Special consideration in the use of servo drives in the model must be placed on the gearbox. It is often used specifically to convert the rotary motion of the servomotor into a linear movement, opens with the example, the gate of a roundhouse and closed. Servo drives are in radio-controlled model plane or ship models have long been common and have a few years Input controls found in the model railroad. Specially tailored to the needs of model railroaders, for example, ESR offers servo drives and from Ulm to provide coordinated accessories below, in terms of the technical and online commerce, information http://www.esu.eu .
