Product Description
The MDD112D-N-040-N2L-130GA2 is a MDD series servo motor from Bosch Rexroth. It supports digital servo feedback. This motor features allows sharing of performance information such as speed and torque with the drive controller. The feedback allows the drive controller to monitor motor parameters and bring them in-line with desired values that are programmed by an operator. According to the motor type code, the frame size is 112, the frame length is D and the housing design is standard (suited to natural convection or surface cooling). Surface cooling is also known as forced air cooling. This cooling method is used for increasing the rate of heat dissipation. The increase in rate of heat dissipation is achieved by increasing the rate of air flow by using cooling fans. The motor shaft is plain. Motor shaft with keyways are also available for MDD motors.
Performance specifications for the MDD112D-N-040-N2L-130GA2 include 4000 RPM nominal speed, 38 Nm continuous torque at standstill, 88.4 Amps continuous current at standstill, 132.2 Nm peak torque, 329.1 Amps peak current, and 120 minutes thermal time constant. Specifications for the motor blocking brake include 40 Nm holding torque, 24 Volts DC voltage, 1.35 Amps current, 150 milliseconds release delay and 30 milliseconds clamping delay. The MDD112D-N-040-N2L-130GA2 is designed for ambient temperatures ranging from 0 to 45 degrees Celsius. It has an IP65 rated housing which is sealed and is completely dust proof. The power connection on the MDD112D-N-040-N2L-130GA2 is on side A of the housing. During transportation and storage, the ambient temperature needs to be kept between -20 and 80 degrees Celsius. Insulation class of the MDD112D-N-040-N2L-130GA2 motor is F. The motor is painted matte black.
