Specifications
- American Rotary's design and development of motor-integrated SoftStart dramatically reduces inrush current required upon start-up so much that our phase converters have the lowest operating cost in the entire industry.
- Taking the initiative to advance phase converter technology, our engineers developed a digital controller to achieve a more reliable and precise method of controlling the start circuit. Digitally monitoring the incoming voltage and automatically making critical adjustments, including shutting down the start circuit if necessary, provides additional protection for the induction generator and the start capacitors. Advanced technology in our digital controller constantly monitors and adjusts voltage balance making our phase converters ideal for CNC and other voltage-sensitive applications. With these advancements, it is no longer necessary to use much less reliable methods (timers and electro-mechanical relays) to control the vital start circuit.
Sizing Help
Determine the load type of the application, and then consult the chart below. Please call us toll free at 1-888-743-6832 for sizing assistance and/or a professional recommendation.
- Easy - no flywheel, clutch, little resistance/inertia, 1-2 times full load current upon start-up
- Medium- machine inertia, medium resistance, 3-4 times full load current upon start-up
- Hard - flywheel, no clutch, starts against load, 5-6 times, or locked rotor current upon start-up
- Very Hard- elevator, hydraulic pump, equipment under continuous load etc
- Frequent Start- instant reversing, heavy running loads
- CNC - turning centers, PLC's, EDM, CNC machining
- Resistive - heaters, transformers, welders, power supplies etc.
