The electromagnets are made of varnished copper. 15 It is produced by winding wires around an iron core. While the motor is running. High current flows through these wires, causing them to heat up. This occurs when the temperature increases, causing the varnish coating to melt or peel. This causes a short circuit. Short circuit In the areas where winding occurs, the temperature suddenly increases, the varnish coating burns, 20 The copper wires are melting and the electromagnet is malfunctioning. This situation needs to be overcome. To achieve this, the electromagnet needs to be cooled, and for this, the stator needs to be cooled. The airflow passing through it is utilized, and additional heat transfer is provided to the engine casing. Surfaces are being added. In the current state of the technology, to better cool the electromagnet windings. Forced airflow is required. To provide this, the outside of the engine... Air inlets and outlets are created in the casing. These air inlets and outlets are of various types. These can be in geometric shapes. However, the motor's inputs and outputs... Depending on the area where the vehicle is used, it can absorb air and rainwater, and 30 There is an influx of dirty water splashing from the ground. These are rainwater and dirty water ingress issues. 9.148 2 It erodes the thin layer of varnish on the copper wires, and the eroded varnish... This layer reduces resistance to heat. Also, it protects against external ingress. The more permeable the materials are, the more electrical connections the electromagnet makes them. A short circuit can be created between them. Therefore, nowadays, the above... Epoxy resin 5 for electromagnet windings to overcome field problems Solutions are needed to ensure it is coated.

The pressure inside the epoxy resin coating tank (3) is 3 atmospheres 25 The valve (6) on the discharge pipe (23) is closed. The coating process starts with the activation of the vacuum pump (4) and the vacuum After the pump (4) is started, the valve (6) on the intermediate pipe (29) is opened to pressure It is observed that the pressure on the indicator (24) is decreasing towards zero. The pressure is 30 After the drop has fallen to an insignificant level, the coating tank (3) and the reservoir (3) 9.148 9 The globe valve (6) between them is opened and the resin in the level tube (16) The position is observed to drop to the marked level. In the level tube (16) When the resin level reaches the marked point, the valve (6) is closed, 10 min. It is expected that the valve (6) on the vacuum pump (4) will be closed, and discharge The valve (6) in the pipe (23) is opened. 5 When the pressure level on the pressure gauge (24) reaches 1 atmosphere, the discharge pipe (23) valve (6) on it is closed and ball valve (5) on compressed air inlet (6) is opened. The pressure inside the epoxy resin coating tank (3) is 2 atmospheres. The temperature is allowed to rise and remains in this state for 20 minutes. Waiting time: 10 after the time period, the ball valve (6) between the reservoir (2) and the coating tank (3) It is opened and now the resin is expected to return to the filling chamber (2). In the chamber (2) When it was observed that there was no increase in the level tube (16), the reservoir (2) and the coating tank The valve (6) between (3) is closed. Then the epoxy resin coating tank The valve (6) on the drain pipe (23) is opened and the pressure is 1 15 When it falls into the atmosphere, the tank lid (21) is removed and slid to the side. Epoxy The stator (S) inside the resin coating tank (3) is pulled out by means of hooks. They are removed and placed in an oven set to a temperature of 80°C for 1 hour. It is left to stand. After 1 hour, the stator (S) is removed and left to cool. is left behind. 20 The subject of the invention is a coating system (1) and a stator (S) coated with epoxy resin. The electromagnet coils are unaffected by external factors and are enclosed in the case for cooling. by maximizing the cross-sectional areas of the opened air inlets and outlets The desired cooling can be achieved. In addition, the air intake and 25 in the stator (S) case Because the outlet areas are increased, the forced air is connected to a fan attached to the motor's rotor. The current can be increased, and pollutants that may enter from outside can affect heat transfer. It does not negatively affect and there is no short circuit between the electrical terminals. It does not occur. In addition, electromagnet windings are made of epoxy resin.
