Product Description

The MDD112D-N-020-N2M-130GB2 is a versatile servo motor. Bosch offers several options for MDD motors that operators can use to match the motors to their requirements. One of these is an optional blocking brake. Blocking brakes are commonly used in servo motors to hold the motor in a specific position when power is not applied. This is useful in applications where the motor needs to hold a load in a specific position, such as in a robotic arm or in a machine tool. Blocking brakes are also used to prevent the motor from moving when it is not in use, helping to reduce wear and tear on the motor and its associated drive system. Bosch offers blocking brakes for MDD112 motor in three holding torque ratings: 14 Nm, 40 Nm and 60 Nm. The bake on the MDD112D-N-020-N2M-130GB2 motor is rated for 40 Nm holding torque.

The brake is an electrically released brake that works at 24 Volts DC and draws 1.3 Amps current. The release delay of the brake is 150 milliseconds and its clamping delay is 30 milliseconds. Mass of the blocking brake is 3.5 kilograms. Mass of the servo motor is 59 kilograms. Therefore the mass of the whole motor package is approximately 62.5 kilograms.  The standard motor housing cools via convection cooling. MDD motors can also be used with surface cooling. The optimal ambient temperature range is 0 to 45 degrees Celsius. The nominal speed rating of the MDD112D-N-020-N2M-130GB2 is 2000 RPM. Motor features include digital servo feedback via an integrated multiturn encoder, a b, 130 millimeters centering diameter and power connection to side B. MDD motors are flange-mounted devices. The size of the flange on the motor is 193 millimeters.
