Problems solved by technology

[0005] A disadvantage of such solutions is also that they are difficult to control, and the control variables for the ventilator have to be adapted, for example, to the control variables for the heating element in order to achieve a certain state at the desired position or to set a certain The heat is sent to the desired position
Furthermore, the complexity of such solutions lies in the need for additional components for the sensing mechanism and heat generation.

Embodiment Construction

[0024] Below in conjunction with embodiment and refer to figure 1 and figure 2 The invention is described in detail, wherein the same reference numerals refer to the same structural and / or functional features in the figures.

[0025] figure 1 A schematic diagram of the system of the air heater 1 according to the present invention is shown. The fan heater 1 has a motor M with a motor winding W and a rotor R, which is connected to a fan V for conveying ambient air. The motor winding is here designed as a heating winding HW for generating a certain heating power or heat. The motor M itself drives the fan V, which then blows air through its windings W and the slots of the motor, thus delivering the heat of the motor windings in a targeted manner.

[0026] figure 2 A diagram showing a control scheme according to the inventive concept. The control concept employs a current and voltage measuring device 10 , a Kalman filter EKF, a controller 30 for field-oriented control of a ...

Abstract

The invention relates to a method and a fan heater (1). The fan heater 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.

Description

technical field [0001] The invention relates to a heater motor and a method for controlling the heater motor. Background technique [0002] The ventilator is used, for example, in combination with a heating element (Heizregister). Commercially available heating equipment such as indoor air heaters, hair dryers, etc. work according to the following functional principle: ambient air is sucked in, heated by the heating element in the system, and then supplied as hot air to the object to be heated or the surrounding environment again. [0003] Such solutions have long been known in the prior art. Publication DE 2308274 B2 provides a purely exemplary implementation. This implementation discloses a hot fan with a housing, a suction opening, a blowing opening and a heating assembly, a radial fan with a fan impeller rotatable around a vertical axis is arranged in the housing, the suction opening is coaxial with the fan impeller, and the blowing opening is The offset is arranged i...
