Product Description

Digital AC servo motors by Bosch Rexroth are characterized by their compact design and high functionality. They are also used to build cost-effective and rapid-response automation systems that are suitable for several applications. The MDD motors are a group of these digital AC servo motors used in robotics and handling machines.

The MDD065A-N-040-N2M-095GB0 is a model of the synchronous servo motors in Bosch Rexroth’s MDD series. Its nominal speed is 4,000 revolutions per minute, and its theoretical maximum torque is 2.3Nm. Based on the design of its housing, it supports cooling by natural convection and surface cooling. Hence, it has a high overload capability since the heat is effectively conducted to the ambient air and the housing. The coating of this housing is a black prime coating that is resistant to weathering, yellowing, diluted acids, and lyes. According to DIN VDE 0530, the motor belongs to the standard Balance Class R, indicating that it is suitable for demanding applications such as grinding machines.

Due to the high power density of the MDD065A-N-040-N2M-095GB0, the motor can be used for dynamic applications like tool changing devices and roller feeds for pressing, punching, and nibbling machines. Its rotor is composed of permanent magnets made of rare earth materials; hence it has low inertia and a favorable torque-to-inertia ratio. The type of motor feedback present in this MDD model is digital servo feedback with an integrated multiturn absolute encoder. This encoder type detects the motor’s absolute indirect position and stores it in the intelligent digital drive. It also has a data memory feature that promotes the servo motor’s rapid startup since it stores important parameters like the motor type name.
