Brushless motors (DC machine)<\/h4>\n

A DC machine is an electric motor that is powered by direct current, or a generator that conversely transforms mechanical energy into AC voltage and then rectifies it.\u00a0In some applications, a device can also perform both functions.<\/p>\n

Built-in motors<\/h4>\n

In the built-in motor, the active motor parts \u2013 the stator with winding and the rotor with shaft \u2013 are installed in the customer housing or machine part.<\/p>\n

Drive systems<\/h4>\n

In technology, drive designates the structural unit that drives energy transformation by means of a machine.\u00a0It is often a motor with the necessary transmission. There are rotary drives and linear drives.<\/p>\n

Drum motors<\/h4>\n

Drum motors are modern drives that combine the gear motor and drive drum in a fixed unit.\u00a0Drum motors were developed as a drive for belt conveyors. Through continuous further development and the use of state-of-the-art materials, drum motors are also used for completely different applications. In general, a drum motor can also be used wherever a drum is currently driven by an external gear motor.<\/p>\n

Disc rotor motors<\/h4>\n

A disc rotor motor is an electric motor whose rotor has the shape of a disc (which is why the disc rotor motor is also known in English as a \u201cpancake motor\u201d).\u00a0In the best-known design, the conducting windings are mounted in the housing. Disc rotor motors are easily recognisable by their design, which is unusual for electric motors (diameter is greater than the length).<\/p>\n

Direct drives<\/h4>\n

Direct drives are drives in which the electric machine and the working machine are directly connected.\u00a0The motor is designed in such a way that its speed is the same as that of the working machine; no transmission is required.<\/p>\n

Typical examples of direct drives are stationary grinding machines, fans, water pumps, linear drives and torque motors.<\/p>\n

Electric motors<\/h4>\n

Electric motors are electromechanical converters that convert electrical energy into mechanical energy. In electric motors, the force exerted by a magnetic field on the conductors of a coil through which current is flowing is converted into motion. Electric motors are the counterpart to the generator. Electric motors usually generate rotary movements, but they can also perform translatory movements. Electric motors are used to drive various working machines and vehicles.<\/p>\n

Freely programmable direct drives<\/h4>\n

Synchronous servo motors, torque motors, linear motors.\u00a0These are operated via an electronic controller. This allows the speed, torque or position to be freely selected.<\/p>\n

Frequency converters<\/h4>\n

are devices based on power semiconductor components that operate in switching mode, i.e. only in the conducting state or in the blocking state. They have the task, especially in speed-adjustable three-phase drive systems, to generate a typically three-phase voltage with a variable frequency and voltage amplitude for powering the three-phase motor from a single-phase or three-phase mains AC voltage with a constant frequency and amplitude. Previously, grids with different frequencies were coupled via rotating frequency converters. However, mechanical systems are still used in railway converting stations.<\/p>\n

Geared motor<\/h4>\n

A geared motor is a combination of a motor (usually an electric motor) and a gearbox.\u00a0It ensures that in most cases the output shaft rotates at a lower speed but with a considerably higher torque than that of the motor.<\/p>\n

High-speed motors<\/h4>\n

High-speed motors run much faster than standard motors.\u00a0There are motors that reach over 100,000 rpm, for example when used in electric turbochargers. This is achieved by a supplying power from frequency converters with a feed frequency of several hundred Hz to over 1000 Hz. The motor is smaller than a standard motor with the same power rating. The rotating parts sometimes have to withstand considerable radial accelerations (centrifugal force).<\/p>\n
