Product Description:
The MHD093B-058-PG1-BA is a three-phase AC servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It combines permanent-magnet excitation with electronic commutation to provide closed-loop motion control for automated transfer lines, packaging machinery, and numerically controlled axes. In these roles, the motor supplies repeatable torque and speed so that the connected drive can position loads accurately under the variable conditions typical of industrial production. Its design supports applications that need responsive acceleration, stable speed regulation, and dependable positioning during repeated start-and-stop cycles.
With a continuous stall torque of 17.5 Nm, the unit can hold static loads without overheating when the shaft is locked. Rotor position and velocity are measured by a digital servo feedback system that includes an integrated absolute encoder, giving the drive an immediate position reference after power-up. The mounting flange measures 140 / 150 mm, while the centering pilot measures 130 mm; these dimensions align the motor precisely to gearboxes or direct-drive frames and help keep radial runout low. Cooling is handled by natural convection, so heat is dissipated through the ribbed housing without external airflow. The motor has frame size 093 and frame length B, giving it a compact format for multi-axis equipment while still supporting the torque demands of industrial motion systems.
A factory-installed holding brake rated at 22.0 Nm secures the shaft during power loss and helps prevent vertical axes from drifting. Power conductors exit through a connector on side B, which can simplify cable routing in compact machine layouts. Winding code 058 identifies the coil resistance and inductance combination used with matched Rexroth drive controllers. Motion is transmitted through a plain shaft with a shaft seal, which helps protect internal components from dust and lubricant intrusion. Absolute position detection over more than 4096 revolutions allows multi-turn position tracking without external reference sensors, which is useful when the axis must retain position information after shutdown or controlled power cycling.
