Product Description:

The MDD093C-N-040-N2K-110GA1 Synchronous Motor is an effective solution from a renowned manufacturer Bosch Rexroth Indramat. It is designed within the advanced MDD Synchronous Motors series and offers efficient operation, robust construction and integrated safety features.

The MDD093C-N-040-N2K-110GA1 synchronous motor rotor has a moderate moment of inertia of 42 × 10⁻⁴ kgm² which help resists changes in speed more and also balances the responsiveness and smoothness of the motor. The motor is equipped with a brake that locks the rotor in place when the motor is unpowered which is crucial for holding a position under gravity or load preventing unwanted movement when power is off. When it is operating under rated conditions it draws 0.8 ampere current which is relatively low and suggests the motor is energy efficient and likely intended for precise or light-duty applications rather than heavy industrial loads. The module outer housing is coated with a black primer, which gives it a standard industrial finish and basic protection against corrosion and wear. The peak torque the motor can deliver before stalling or failing is 60.6 nm which suggests it can handle high starting or overload conditions for short periods.

The continuous rotational speed on which MDD093C-N-040-N2K-110GA1 synchronous motor can run is 4000 min⁻¹ which is relatively high that makes it suitable for fast operations like high speed machining or rapid movement systems. It has a mass of 22 kg which is fairly substantial and indicates a solid construction with significant materials. The side or orientation where electrical connections of this module are made is A. It heats up or cools down under constant load in 50 minutes. The maximum operating temperature of the motor’s winding insulation is 155°C.

Frequently Asked Questions about MDD093C-N-040-N2K-110GA1:

Q: How does the blocking brake enhance the safety of the MDD093C-N-040-N2K-110GA1 motor?

A: The brake prevents shaft rotation when the motor is unpowered, holding the load securely in position. This is crucial for vertical axes and safety-critical tasks.

Q: Why is a moment of inertia of 42 × 10⁻⁴ kgm² suitable for precision applications?

A: It provides a balance between responsiveness and smooth speed transitions. This helps reduce vibration and improve motion accuracy in dynamic systems.

Q: How does the nominal current of 0.8 A contribute to the motor’s operational efficiency?

A: Lower nominal current reduces overall energy consumption. It also minimizes heat generation, allowing for longer continuous operation with less thermal stress.

Q: What advantage does the RAL 9005 black primer coating offer to MDD093C-N-040-N2K-110GA1?

A: This coating provides resistance to corrosion and mechanical wear. It extends the motor’s operational lifespan in demanding industrial environments.

Q: Why is a 50-minute thermal time constant beneficial in MDD093C-N-040-N2K-110GA1?

A: A longer thermal time constant allows more time before thermal limits are reached. This supports higher duty cycles and short bursts of peak load.
