Product Description

The Bosch Rexroth MHD115A-058-NG1-AA is a servo motor. It is designed specifically for industrial applications. The motor is typically deployed in combination with a servo controller. The power socket is on side A of the motor housing. The power cable from the controller terminates on this power socket. Housing of the MHD115A-058-NG1-AA is suited to natural convection and surface cooling. Natural convection relies on the flow of air over the heated motor body. Surface cooling relies on the flow of air at a higher rate of flow over the motor. This higher rate of air flow is created by a cooling fan or blower. The motor is designed for 0 to 40 degrees Celsius ambient temperature. At higher ambient temperatures the internal motor temperature will exceed safe limits. This will cause output derating and can also lead to component malfunction or failure.

The MHD115A-058-NG1-AA motor is supplied with a holding brake. The function of this brake is to prevent shaft startup from standstill. It is a safety feature that is designed to prevent accidental machine movements. The brake is rated for 70 Nm holding torque and only releases the motor shaft after application of a 24 Volts DC signal. The main motor shaft is plain and includes a sealing ring. The MHD115A-058-NG1-AA motor also supports digital servo feedback. This features enables sharing of motor parameters with the drive controller. This in turn allows the controller to monitor motor parameters and to bring them in line with desired values. Mechanical specifications for the MHD115A-058-NG1-AA include 30 kilograms weight, 370 millimeters motor length, 180 millimeters centering diameter and 192 millimeters flange size. Each mounting hole on the flange has a diameter of 14 millimeters.
