Product Description:
The MHD093A-058-PG0-BN, manufactured by Bosch Rexroth Indramat, belongs to the MHD Synchronous Motors series. This MHD093A-058-PG0-BN servo motor delivers controlled rotary motion for numerically controlled machine axes, conveying stages, and handling equipment. It works with compatible Indramat drive controllers to convert electrical commands into precise mechanical output for positioning and speed-controlled tasks. Its design follows the platform used for liquid-cooled synchronous motors, making it suitable for applications that need high power density, compact footprints, and stable thermal behavior during sustained duty.
At standstill, the motor can continuously deliver 12.0 Nm of torque, and its liquid cooling jacket removes stator heat during operation. The sealed housing has an IP65 protection rating, while the windings use Class F insulation for 155 °C thermal endurance. Operation is permitted in ambient air from 0 to 40 °C, and installation alignment is aided by the 130 mm centering diameter. The motor does not include a holding brake, so position retention must be handled by the drive or external mechanics. The plain shaft transfers torque without a keyway, which suits clamping or friction-based couplings. Power is routed through a connector on side B, and the short A length in size 093 helps reduce installation space.
Feedback accuracy is ±0.5 angular minutes, supported by an optical encoder system with absolute (>4096 revolutions) tracking. The 140 / 150 mm square flange fits standardized gearbox and mounting plate interfaces, and the integrated shaft seal helps limit coolant ingress at the shaft opening. Installation is permitted up to 1000 m above sea level, and storage temperatures can range from -20 to +80 °C. The optical measurement system supplies position data for commutation and closed-loop control during operation.
