Product Description

The Bosch MDD090B-N-020-N2M-130PB2 is an AC motor. It is part of the MDD product line. Rated speed of the motor is 2000 RPM. The motor housing is suited to natural convection and surface cooling. Balance class of the MDD090B-N-020-N2M-130PB2 motor is standard. The side B shaft end is standard (without side B shaft end). The shaft includes a keyway that prevent relative rotation. The benefit of a keyway is effective transfer of torque to the connected machine. The power connection is located on side B of the housing. Customers need to order the power connector separately. An integrated multiturn encoder enables digital servo feedback. The encoder measures motor speed and torque and sends this information to a connected drive controller. The controller uses feedback from the motor to adjust its output.

The blocking brake on the MDD090B-N-020-N2M-130PB2 is rated for 11 Nm holding toque, 24 Volts nominal voltage and 0.5 Amps current draw. The brake is designed to prevent shaft rotation at standstill. Moment of inertia of the brake is 0.000106 kg m². Clamping delay of the blocking brake is 20 milliseconds and its release delay is 60 milliseconds. The mass of the blocking brake on the MDD090B-N-020-N2M-130PB2 is 0.5 kilograms. The mass of the servo motor is 18 kilograms. Therefore the total mass of the package is 18.5 kilograms. Relevant guidelines related to motor handling are included in the product documentation. The bigger and thus heavier motors may only be transported with the use of suitable lifting devices as described in the documentation. The motors should only be mounted to the machine by fully trained personnel. The motor must be grounded to the drive amplifier.
