Frequently Asked Questions
How does the continuous torque of 3.7 Nm affect motor use in heavy-duty applications?
The 3.7 Nm continuous torque ensures reliable operation in medium-load environments but may limit the motor's use in heavy-duty applications that require more torque or dynamic load handling.
What effect does the 21.9 A maximum current have on MDD090A-N-020-N2L-110PB1 motor performance during load changes?
The 21.9 A maximum current ensures the motor can provide sufficient power during load fluctuations, maintaining consistent performance and minimizing the risk of overload in dynamic applications.
Why is a 0.45 Ohm windings resistance critical in power-efficient designs?
The windings resistance of 0.45 Ohm contributes to power losses as heat. In power-efficient designs, minimizing this resistance is crucial to reduce energy loss and maintain optimal motor efficiency.
How does the nominal speed of 2000 min⁻¹ impact the motor's performance under varying loads?
The 2000 min⁻¹ nominal speed provides a balanced performance for most medium-load applications, offering good control and stability without compromising efficiency or power output under typical load conditions.
What are the potential challenges when using a keyway shaft for coupling?
While a keyway shaft provides secure torque transmission, it can increase installation complexity and may introduce alignment issues if not properly aligned, which could lead to system inefficiencies.
