Product Description:

The MHD115B-058-PP0-AA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It converts regulated drive current into precise rotary motion for positioning axes, conveyor sections, and packaging tooling in automated machinery. Because the motor uses an integrated encoder and is intended for closed-loop operation with compatible Rexroth drive controllers, it supports repeatable start-stop cycles and stable velocity control. This operating arrangement helps the axis respond accurately to commanded motion while maintaining consistent positioning during changing load conditions.

A centering feature of 180 mm aligns the housing concentrically to the machine plate, while the square flange measures 192 mm across for four-bolt attachment. The magnetic circuit and winding selection allow a continuous standstill torque of 50.0 Nm, so the shaft can hold load torque without external gearing when drive current is applied. Heat is removed by natural convection, which eliminates the need for a fan or liquid cooling jacket and keeps the motor layout simple. Command feedback is provided through digital servo feedback, allowing the drive to correct position error during each control cycle and maintain accurate motion over repeated operating sequences.

The motor uses a keyed shaft interface for slip-free coupling to pulleys or gear hubs. It is supplied without a holding brake, so vertical or suspended loads require external holding force or drive-produced torque when power is removed. Absolute position reporting over 4096 revolutions reduces the need for homing after startup and supports axis recovery after controlled shutdowns. Winding designation 058 identifies the electrical winding arrangement used for this torque class, and power conductors exit on side A through a sealed output connector that preserves the enclosure boundary during operation.
