Product Description

The MDD112D-N-040-N2M-130GA1 is a Bosch Rexroth MDD motor. It is designed to be used in combination with drive controllers from Bosch. The motor supports digital servo feedback with integrated multiturn absolute encoder. This motor feature enables the connected drive controller to learn about the motor speed, position etc and to control the motor so that that parameters comply with desired values. The MDD112D-N-040-N2M-130GA1 motor also includes a blocking brake rated for 14 Nm. The principle of action of the bake is electrically actuated release. The brake is designed to be released at 24 Volts DC. The nominal current for the brake is 0.75 Amps. The release delay for the brake is 70 milliseconds and the clamping delay is 30 milliseconds. The weight of the blocking brake is 1.1 kilograms.

The motor MDD112D-N-040-N2M-130GA1 features a power connection on side A of the motor housing. The main shaft on the motor is plain. The nominal motor speed is 4000 RPM. The motor housing design is standard and is suited for natural convection and surface cooling. Environmental specifications for the MDD112D-N-040-N2M-130GA1 include 0 to 45 degrees Celsius operating temperature, -20 to 80 storage / transportation temperature and 0 to 1000 meters elevation. The continuous torque and current ratings are 38 Nm and 88 Amps. The winding on the MDD112D-N-040-N2M-130GA1 has a resistance of 0.05 Ohms at 20 degrees Celsius. The winding inductance is 0.7 millihenry. The thermal time constant for the MDD112D-N-040-N2M-130GA1 is 120 minutes. The weight of the servo motor is 59 kilograms. Optimal motor performance can only be achieved if it is installed properly. Therefore only qualified and trained personnel should be allowed to install and operate the motor.
