Abstract
A fan heater (1) has a motor (M) with motor windings (W) and a rotor that is connected to a fan (V) for delivering ambient air at least partially along the motor windings (W). At least one motor winding is configured as a heater winding (HW) for generating a specific heat output or amount of heat as intended.
Claims12
A fan heater comprising:
- a motor with integral motor windings, the motor windings positioned in a groove inside a motor housing and a rotor which is connected to a fan for delivering ambient air along the motor windings in the grooves, and at least one motor winding, of the motor windings positioned in the groove in the motor housing, is configured as a heater winding for generating a specific heat output or amount of heat as desired.
A fan heater comprising:
- a motor with motor windings, the motor windings positioned in a groove inside a motor housing, and a rotor is connected to a fan for delivering ambient air along the motor windings in the grooves, and at least one motor winding, of the motor windings positioned in the groove in the motor housing, is configured as a heater winding for generating a specific heat output or amount of heat as desired;
- and
- the temperature of the heater winding and/or the rotor position of the rotor of the motor is detected or operated by a Kalman filter.
A fan heater comprising:
- a motor with motor windings and a rotor is connected to a fan for delivering ambient air along the motor windings, and at least one motor winding, of the motor windings, is configured as a heater winding for generating a specific heat output or amount of heat as desired;
- and
- temperature of the heater winding is controlled by a d portion of a field-producing current (id), separately from speed of the motor.
