Frequently Asked Questions
In what kind of application would the motor excel due to its specified features?
The motor is ideal for CNC machining centers, packaging machines or automated assembly lines where high torque at low speed, IP65 protection and tight servo feedback loops are required. It supports rapid positioning and accurate motion control in demanding industrial processes.
Why is the thermal time constant, cited as 50 min, relevant for the MDD090C-N-020-N5L-130GA0 motor?
A thermal time constant of about 50 minutes means the motor’s winding temperature responds slowly to load changes, allowing short bursts above continuous ratings without exceeding thermal limits. It aids in duty-cycle planning for high-duty operations.
What does the theoretical maximum torque of 45.1 Nm indicate for this motor?
The theoretical max torque of 45.1 Nm represents the peak torque the motor can deliver for short durations. It indicates headroom for transient loads, such as rapid start-stop cycles or unexpected load spikes.
How does the 130 mm centering diameter of the MDD090C-N-020-N5L-130GA0 motor benefit mechanical integration?
A 130 mm centering diameter provides a standard mounting interface compatible with many mechanical systems, facilitating retrofit and modular design. It simplifies coupling alignment and reduces installation time.
What role does the IP65 protection rating play for this motor in industrial settings?
The IP65 rating ensures the motor is dust-tight and protected against low-pressure water jets, allowing use in harsh factory environments. This increases uptime and reliability under wash-down or dusty conditions.
