Product Description:

The MHD093A-035-PP0-AA is a three-phase servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. As a frame size 093 unit, it works with digital drive controllers to deliver commanded torque and speed profiles for tooling stations, indexing tables, and handling modules. The integrated absolute encoder allows the controller to resume motion without re-homing after a power loss, which helps reduce startup delays in automated systems. This arrangement supports closed-loop operation in machines that require repeatable starts, stops, and speed changes during long production runs.

At standstill, the motor delivers a continuous torque of 12.0 Nm, so some applications may not require a separate mechanical holding device. Precise alignment is supported by a 130 mm centering shoulder and a square mounting flange of 140 / 150 mm, which helps the motor seat accurately on the machine interface. The motor is sealed to IP65, and the fitted shaft seal helps keep coolant spray and airborne particles away from the bearing chamber. Rotor position is measured by digital servo feedback, using an optical system to record absolute values across more than 4096 revolutions while maintaining high positioning accuracy. Heat is removed through natural convection across the ribbed aluminum housing, so no fan or liquid cooling circuit is required.

Permissible operating temperatures range from 0 to 40 °C, while long-term storage is allowed from -20 to +80 °C; both ranges assume installation up to 1000 m above mean sea level. The windings use class F insulation, and the motor has a keyed shaft for positive torque transfer to pulleys or couplings. Electrical power enters through a connector on side A of the stator, which matches the stated connection direction. The motor uses winding code 035 and length designation A, and it operates without a holding brake, so the drive must maintain position when power is removed.
