The present disclosure is directed to a system and method for reducing ice or condensation that forms on a power component of a wind turbine during a power outage. The method includes determining an ambient temperature near the power component; providing one or more parameters of the power component; determining a down time of the power component for the power outage; determining a wait time for the power component to stay offline as a function of the ambient temperature, the one or more parameters, and the down time of the power component; and, heating the power component for the wait time before supplying power to the power component such that a surface temperature of the power component is raised above the ambient temperature. As such, the method prevents the power component from being energized when condensation or ice may be present.

A method for sanitizing an electric motor is provided. The method includes setting operational parameters for the electric motor for destroying targeted microbes; and energizing the electric motor using the set operational parameters. Computer program products and an electric motor are disclosed.

The present disclosure relates to systems and/or methods for monitoring one or more motor space heaters. For example, various embodiments described herein can relate to a method for monitoring one or more motor space heaters that includes detecting that an electric motor is inactive based on operation data generated by a sensor circuit coupled to the electric motor. Additionally, the method can include determining, in response to the detecting, whether a motor space heater in proximity to the electric motor is active based on the operation data. Also, the sensory circuit can be further coupled to the motor space heater.

A method for producing a component for an electrical machine, the component has a magnetic core with at least one groove which receives at least one wire winding, runs parallel to a longitudinal central axis of the component and completely penetrates the magnetic core. The component is aligned during introduction of an impregnating agent into the at least one groove in such a way that the impregnating agent is forced into the at least one groove in the direction of the longitudinal central axis by the influence of gravity. A temperature of the at least one wire winding is initially set to a lower first temperature selected to reduce a viscosity of the impregnating agent and then to a higher second temperature selected to increase the viscosity of the impregnating agent by applying an electric current during introduction of the impregnating agent into the at least one groove.

A ram air turbine assembly includes one or more airfoils and a ram turbine operably connected to the one or more airfoils. The ram air turbine includes: a rotor; a stator that includes windings; and a self-regulating heater coupled to the stator. The self-regulating heater configured to vary power that passes through it based on a temperature of the heater.

Aspects of the present disclosure relate to self-heating electric motor control. In examples, a motor controller includes a normal control scheme and a heating control scheme, whereby the heating control scheme causes the electric motor to produce heat (in addition to or in the absence of mechanical operation of the electric motor). For example, if the electric motor has cooled below a minimum operating temperature, the heating control scheme is used to heat the electric motor prior to mechanical operation of the electric motor. As another example, the electric motor may approach or fall below a minimum operating temperature during operation, such that the heating control scheme is used to cause the electric motor to produce additional heat while in operation. Thus, the electric motor is heated as a result of the heating control scheme, as are one or more associated mechanical or electrical components.
