Product Description:

Bosch Rexroth Indramat has developed the MDD093B-N-040-N2K-110PA0 that is a Synchronous servo motor. It is well-known for its capacity to offer accurate motion control in automated systems, and it is a part of the MDD series. The motor's nominal speed is 4000 min⁻¹, and it is designed for use in compact machine layouts.

Surface cooling makes the motor produce a steady power of 20.0 Nm when it is not moving. It can keep a steady current of 50.5 A when it is cooled from the surface. The servo motor MDD093B-N-040-N2K-110PA0 servo motor can handle up to 164.8 A of power at its peak. A torque constant of 0.40 Nm/A makes sure that the torque generated per ampere stays the same. If it is 20°C outside, the windings have an inductance of 1.9 mH, and their resistance is 0.14 Ohm. The servo motor comes with a standard output shaft that has a keyway that meets DIN 6885 sh. 1, 8/68 edition. This makes it easier to connect securely to load elements. The servo motor's weight of 16.5 kg acts as a mix between its torque output and mounting stability. In industrial automation settings, the MDD093B servo motor is made to do precise drive tasks.

For direct installation arrangements, the motor is designed with a casing that prevents the shaft end from side B. The rate of temperature increase during operation is determined by the thermal time constant of 50 minutes. A power connector is affixed on side A of the motor. The servo motor is also constructed without a blocking brake, which reduces design requirements in situations when static holding torque is not required. Specific thermal and electrical factors help to ensure the MDD093B-N-040-N2K-110PA0 servo motor's operational precision. This motor's integration allows consistent torque transfer in machines with continuous motion patterns.
