Product Description:

The MDD090C-N-030-N2K-110PB1 Synchronous motor from Bosch is designed for precise and reliable operation in automation. At 24 kg, the motor is a member of the MDD series. The motor manages heat dissipation well by supporting methods such as natural convection and surface cooling.

The MDD090C-N-030-N2K-110PB1 synchronous motor offers a natural convection torque of 10.40 Nm with a current of 19.50 A. When the surface is cooled, it delivers a higher torque of 16.00 Nm at 30.00 A current. The nominal speed is 3000 revolutions per minute. The torque constant is 0.53 Nm/A, indicating the torque produced per ampere of current. The motor has a cylindrical steel shaft with a keyway, which has rusted due to use. The flange is square with four mounting holes and additional small bore holes, designed for secure attachment. The power connector is a circular multi-pin male type with a threaded metal locking mechanism. The feedback or encoder connector is a female circular type with gold-plated multi-pins, likely for a resolver or encoder. Both connectors are top-mounted and aligned side by side.

The MDD090C-N-030-N2K-110PB1 motor is a great choice for industrial automation tasks that need efficient control and long-term dependability. This motor is made to work in places with dust and water because it has an IP65 security grade and an insulation class of F. The holding brake works at 24 V DC and makes 6.5 Nm of power. It has a current tolerance of ±10% and a current of 0.5 A. Because the gears are greased and there are no brushes, the motor can run continuously without needing to be serviced. Because it has an IP65 rating, internal parts are safe from dust and water getting in. Thermal management is made more versatile with the combination of surface cooling and natural cooling alternatives.
