Product Description:

The MDD093C-N-030-N2K-110GB1 is one of the Synchronous servo motors available from Bosch Rexroth Indramat. This MDD series motor is ideal for applications requiring steady torque and precise motion control. The MDD093C servo motor can be easily integrated into automation systems that provide controlled acceleration and braking capabilities and run on continuous cycles.

The MDD093C-N-030-N2K-110GB1 synchronous servo motor has a maximum operating speed of 3000 RPM. With a maximum current rating of 145.0 amps, the motor can give transient torque boosts for acceleration. The servo motor has a theoretical maximum torque of 60.6 Newton-meters. The torque constant of 0.61 N/mA is maintained at 20°C. The winding's resistance of 0.23 Ohms at 20°C is one of the components that contribute to current control and heat distribution. The normal housing makes the motor appropriate for surface cooling and natural convection. In a controlled setting, the housing keeps the interior components stable. The MDD093C motor is designed to satisfy the demands of applications requiring a conventional power-to-length ratio. Its dimension is 093 and its length is C. The motor includes the DIN VDE 0530 standard balancing class R. To be compatible with some single-ended connection techniques in automation systems, the device lacks a shaft end on side B.

The centering diameter of MDD093C-N-030-N2K-110GB1 servo motor is 110 millimeters, allowing for precise alignment with drive components. When the motor is at rest, an 11.0 Nm blocking brake maintains a steady holding torque. At a complete stop, the current flowing constantly is 32.2 amps. The design incorporates conventional mechanical characteristics to provide stability during dynamic motion cycles. MDD093C servo motor can be used in industrial automation systems that require synchronization of multi-axis movements. The specifications align with application demands that prioritize consistent torque output and regulated current levels. The servo motor is designed for tasks where secure holding at a standstill and thermal regulation are essential.
