Product Description:
The MHD093C-058-NG0-BA is a synchronous AC unit manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Classified as a servo motor, it provides closed-loop torque and speed control in machining centers, material handling stations, and packaging modules. Its synchronous design allows the connected drive to regulate acceleration, running speed, and holding behavior with stable response during repeated motion cycles. Relative position detection is performed by the integrated encoder, which supports precise velocity and position control in the drive controller.
Mechanically, the motor has a centering diameter of 130 mm, allowing rigid seating against the machine flange that measures 140 / 150 mm. With motor size 093 and length code C, the housing accommodates the laminated core while keeping the frame suitable for mid-range machine axes. At standstill, the electromagnetic circuit delivers 23.0 Nm of continuous torque, which suits medium-inertia loads during sustained operation. Heat is removed through natural convection, so no external blower or coolant loop is required. A plain shaft transmits torque directly to couplings or gearboxes, which supports straightforward integration with common driven elements. Power conductors terminate on an output connector, and the motor is supplied without a holding brake.
The feedback channel is handled by a digital servo feedback (HSF) encoder that streams incremental count and commutation data to the Rexroth inverter. This sensor arrangement provides high-resolution feedback for dynamic motion control without using an absolute track. A shaft seal is present, so the bearing cavity remains isolated from coolant mist or fine dust during high-cycle operation. Electrical behavior is matched to winding code 058, which uses a coil set intended for medium-voltage bus operation and fast current response. For streamlined cabinet layout, the power connector faces to side B, helping keep the cable bundle aligned with adjacent axes and reducing routing interference around the motor body.
