Frequently Asked Questions
Common questions about the ND Series
What is the advantage of a synchronous motor over an induction motor?+
A synchronous motor maintains constant speed regardless of load — its speed is locked to the supply frequency. An induction motor speed varies slightly with load (slip). For timing and metering applications where speed accuracy is critical, synchronous is the correct choice.
What does the gear ratio range 1:15.6 to 1:1400 mean in practice?+
At a 1:1400 ratio with a 1500 r/min motor, output speed is approximately 1 r/min. At 1:15.6 it is around 100 r/min. This ultra-wide range means a single motor family covers timing speeds from very slow (1 RPM) to moderate (100 RPM).
Can the ND Series motor reverse direction?+
Direction reversal requires wiring changes. Please refer to the wiring diagram provided with the motor, or contact us for guidance on your specific configuration.
Is this motor suitable for 24/7 continuous operation?+
Yes. With pure copper winding and Class F insulation, the ND Series is rated for S1 continuous duty. It is commonly deployed in 24/7 timing and metering applications.
