Product Description:
The MHD093A-058-NG1-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It converts electrical energy into precisely regulated rotary motion for positioning tasks on automated conveyors, packaging stations, and machine tool axes. A digital servo feedback encoder supplies high-speed signals to the drive controller, while relative position detection and an optical measurement principle support a short control loop. The motor housing accepts a liquid cooling jacket, and power is routed through an output connector on side B of the stator.
The unit supplies a continuous standstill torque of 12.0 Nm, giving the axis ample holding force during static machining or dwell periods. An integrated holding brake rated at 22.0 Nm locks the shaft when system power is removed, helping prevent drift on vertical loads. The motor is sealed to IP65, so dust and water jets do not affect internal components. Heat is removed through liquid cooling, allowing full current delivery even inside tight cabinets. Mechanical centering on the mounting face uses a 130 mm pilot diameter, and the 140/150 mm flange helps align the motor to precision gearboxes. Winding code 058 identifies the stator conductors.
Positioning accuracy is ±0.5 angular minutes, which supports repeatable index moves without external encoders. Storage temperatures from -20 to +80 °C protect the magnet array during transport, while operation is limited to 0 to 40 °C to maintain bearing life. Installation heights may reach 1000 m above mean sea level without derating. A shaft seal is fitted, and the plain shaft design eases coupling to belt pulleys or clamp hubs. The motor length code A and size 093 keep the package compact, and insulation class F allows higher winding temperatures before thermal protection is triggered.
