- Stator-Super Thin (0.2mm) laminations
- Precision engineered for maximum energy conversion
Voltage recommendations in the table below are guidelines for the voltage you can safely run. It is still critical that the user monitor motor temps and adjust gearing if necessary, any motor can overheat to the point of destruction if over-geared even when running at or below the rated voltage.
