Rotation speed setting resistor |
| 摘要 |
<p>A rotation speed setting resistor for a load circuit of a fan electric motor, especially a vapour extraction hood, having at least one tap, in the case of which resistor the resistance body is formed as a flexible resistance film and, in order to dissipate the heat losses produced in the resistance material, surrounds the fan airflow in a shape which is matched to the circumference of the flow duct of an airflow produced by the fan.</p> |
