Sensorless Control of Segment Fan Motors 2005-01-2015
Johnson Electric has designed a cooling fan motor specifically focused on meeting the demand for the high-power segment of the cooling fan market. This market is not presently covered by any comparable system. The current design provides 4200m3/hr airflow @ 280 Pa using 865 W power and has an overall depth of 78 mm. In addition, because of the high torque/low speed operation, it is possible to deliver such significant airflow with low noise.
