Product Description:

The MDD093C-N-030-N5L-110PA2 is an AC servo motor from Bosch Rexroth renowned MDD Synchronous Motors family. The module features permanent magnet technology, integrated holding brakes and various cooling options which makes it ideal for demanding industrial automation, robotics and CNC applications.

The MDD093C-N-030-N5L-110PA2 motor brake takes about 60 ms to release after power is applied which means it can engage quickly after being held in a stopped state. Under self cooling the continuous current required is 34.30 A which reflects how much electrical current the motor draws when it's externally cooled like with a fan or blower under continuous operation. It can manage 32.2 amps current continuously when it is not rotating. When it is cooled only by natural air flow the continuous torque output the motor can deliver is 19.50 Nm which shows how much turning force is available in basic cooling conditions. It has a nominal speed of 3000 RPM which is a standard speed for servo motors and indicates a balance between torque and speed. Its brake mechanism is electrically actuated release which means it releases when electric power is applied . To hold the rotor stationary when not energized it is equipped with a brake which is common in vertical load or positioning systems to prevent back driving.

The safe temperature range for storing or moving the MDD093C-N-030-N5L-110PA2 motor without damaging internal components is -20 to +80 °C. The electrical resistance of the motor's windings measured at room temperature is 0.12 Ohm which affects how much power is lost as heat and impacts performance and thermal design. For surface cooling the torque rating is 20 Nm which reflects a slightly higher torque capacity than with natural convection.

Frequently Asked Questions about MDD093C-N-030-N5L-110PA2:

Q: How does the 0.12 Ohm winding resistance affect the motor's thermal performance?

A: Lower resistance reduces power losses as heat, increasing efficiency. It helps the MDD093C motor maintain stable performance during extended operations.

Q: Why is a brake with electrically actuated release used in MDD093C-N-030-N5L-110PA2?

A: It ensures the brake engages when power is off, offering fail-safe functionality. This design is vital for vertical loads and precision holds.

Q: What role does the IP65 protection rating play in this motor’s performance?

A: IP65 protection safeguards against dust and low-pressure water jets. This enables the MDD093C-N-030-N5L-110PA2 to operate in harsh industrial environments.

Q: How does surface cooling increase the motor’s torque capability?

A: Surface cooling dissipates heat more effectively, allowing continuous higher torque. The MDD093C-N-030-N5L-110PA2 achieves 20 Nm compared to 19.50 Nm with natural cooling.

Q: Why is a 60 ms brake release delay important for MDD093C-N-030-N5L-110PA2?

A: Quick brake release ensures minimal startup delay. It's beneficial for time-critical applications like robotics or automated tooling systems.
