Product Description:

The MHD090B-035-PP0-UN/S002 is a three-phase servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is used as an AC servo actuator in industrial machinery, where it converts commanded electrical energy into controlled rotary motion. By linking the drive electronics to the working load, it supports repeatable positioning on machining centers, printing presses, and conveyor stations. It is suited for applications that need stable motion during frequent acceleration, deceleration, and indexing sequences.

The motor provides a continuous standstill torque of 12.0 Nm, which allows it to maintain load at zero speed during dwell periods without excessive heating. Its enclosure carries an IP65 rating, helping keep out dust and low-pressure water jets commonly found in production areas. Heat is removed by liquid cooling, which supports steady thermal control during demanding duty cycles. Position feedback comes from a digital servo encoder with optical measurement and a system accuracy of ± 0.5 angular minutes. A centering pilot of 110 mm and a 140 mm square flange help align the motor with standard machine interfaces, and the encoder feedback allows the control loop to correct speed and position errors as load conditions change.

Continuous operation is permitted in ambient temperatures from 0 to 40 °C, and the power connection can be rotated through 270° to simplify cable routing in tight machine spaces. The winding uses insulation class F, which supports internal temperatures up to 155 °C during normal thermal loading. Torque is transmitted through a keyed shaft with a shaft seal, and separate power and feedback connectors keep the electrical interfaces organized. The motor has size 090, length code B, and winding code 035. It also supports absolute position detection over more than 4096 revolutions, is supplied without a holding brake, and can be installed up to 1000 m above sea level.
