Product Description

MHD motors are digital alternating current (AC) motors developed and manufactured by Rexroth Indramat. They are designed to function in combination with high-end drive controllers from the company to form an economically viable drive system. Electric motors in the Rexroth MHD series boast a broad spectrum of functionalities in areas such as textile machines, handling systems, machine tools, etc. They offer high power data, flexible mounting orientation, high dynamics, zero maintenance operations, and overload protection. As per the design, MHD motors are classified as permanent magnet devices with minimal inertial masses.

This model, in particular, the MHD093B-024-NP0-BA, is a high-performance motor in the MHD product group. The design of this motor does not include a holding brake; hence, a safe standstill of its axis when it is de-energized cannot be achieved. It is available with a drive shaft with a keyway, and it utilizes a natural convective cooling technique. The MHD093B-024-NP0-BA comes with a basic black coating, and it is resistant against alkaline solutions, weathering, undiluted acids, chalking, and yellowing. The rated speed of this motor is 2000 RPM, and its thermal time constant is 40 mins. In addition, it has a peak current of 34.2 A and a theoretical max. torque of 44 Nm.

The installation elevation of this digital AC motor is between 0 – 1000 meters, and its ambient temperature must be between 0 – 45 degrees C for optimal performance. If the nominal data of the MHD093B-024-NP0-BA are exceeded, its load factor must be considered. This unit’s liquid cooling mechanism has a rated power dissipation of 900 Watts and a maximum pressure of 3 bar. Furthermore, the coolant channel has a volume of 0.05 L.
