Product Description
The Bosch MDD112B-N-030-N2L-130PB3 is a servo motor. Together with digital drive controllers, the motor is deployed for cost-effective and rapid-response automation systems. Drive systems with MDD motors are well suited to applications such as textiles, printing machines, and transfer facilities. The MDD112B-N-030-N2L-130PB3 has a rated speed of 3000 RPM. Its housing is IP65 rated and is painted black. The motor housing has a standard design. Customers can use the motor with either natural convection or surface cooling. The load requirements will dictate the choice of cooling method. Higher motor torque and current output are possible with surface cooling. Therefore surface cooling is more appropriate for higher load requirements. With surface cooling, the continuous motor torque at standstill is 21.4 Nm, and the continuous motor current is 34.3 Amps. With natural convection, the continuous motor torque at standstill is 17.5 Nm, and the continuous motor current is 28 Amps.
The motor thermal time constant is an indicator of the heat capacity of a motor's windings and outer case; a measure of to what degree a motor stores internal heat. The thermal time constant for the MDD112B-N-030-N2L-130PB3 are varies with cooling method used. With surface cooling the thermal time constant is 60 minutes. With natural convection the thermal time constant is 90 minutes. The MDD112B-N-030-N2L-130PB3 supports digital servo feedback. The main shaft includes a keyway as per DIN 6885-1. The purpose of the shaft keyway is to facilitate torque transfer through prevention of relative rotation. The MDD112B-N-030-N2L-130PB3 also features a 60 Nm rated blocking brake. Customers can specify the direction of the power connection. On the MDD112B-N-030-N2L-130PB3 motor, the power connection is on side B of the housing.
