Product Description

The MHD synchronous motors are products designed by Bosch Rexroth. Like other works by this manufacturer, they are top-quality innovations with a wide range of applications. These motors are constructed with unique magnet materials, which enable them to have low inertia. They are commonly used in machine tools, printing and paper industries, handling and automation systems, food and packaging machines, etc.

The MHD112D-027-NP0-AN is an MHD motor of frame size 112, which means that it has a centering diameter of 130mm and a flange size of 192mm. It is a permanent magnet synchronous motor characterized by high operational reliability and high-performance data. The motor has four pole pairs and a moment of inertia of 350 x 10⁻⁴ kgm². Its housing design supports the application of natural convection or surface cooling as a cooling method. In addition, its bearing is designed for high radial loads; thus, belt pulleys and pinions can be directly suspended. It is also equipped with a digital servo feedback encoder and a plain output shaft with a shaft sealing ring. The shaft is mounted with a friction-locked shaft hub connection.

The maximum speed of the MHD112D-027-NP0-AN is 3,000 revolutions per minute, and its rated frequency is 133 Hz. At 20°C, its voltage constant and winding resistance values stand at 154.5V/1000min⁻¹ and 0.35 Ohms, respectively. It features a temperature monitoring system that protects it from damage due to overload. Its lifetime-lubricated bearings and brushless design also allow it to be operated maintenance-free. During installation, it should be set up at a maximum height of 1000m above sea level. Also, it is best operated at a temperature range between 0°C and 40°C.
