Germany Marzahl Germany Marzahl Vertrieb long-term production and supply of motors, gear products, its products get the praise of customers. Marzahl Vertrieb provide complete machine tools and automation technology product range. Especially in high technical standards and to the field of special gear for each application, we provide an optimal solution. Marzahl Vertrieb servo motor control is the operation of the mechanical components in the servo system of the engine, the transmission is a motor indirect subsidies. Can control the speed of the servo motor, position accuracy is very accurate, the voltage signal may be converted to torque and speed to drive the control object. Rotor speed servo motor controlled by the input signal, and can quickly react, in the automatic control system, used for the implementation of components, and has a small mechanical and electrical time constant, high linearity, initiating voltage and other characteristics of the electrical signal to be received converted into angular displacement or angular velocity of the motor output shaft. DC and AC servo motors into two categories, its main feature is that no rotation phenomenon when the signal voltage is zero, the speed increases torque and uniform decline. The product range includes modern tools and gear drives and servo servo angle planetary gear reducers, servo worm gear and rack and cooling devices. Main models: PG series, PGE series low backlash (zero backlash) gear ratio transmission speed gearbox transmission ratio gear system of special gear system special worm gear worm gear planetary gear transmission planetary gear drive bevel gear bevel gear bevel gear mechanism, a large bevel gear mechanism, a large bevel gears, small bevel gears, small
