Problems solved by technology

[0010] Brushless motors, which consist of a set of vanes fixed to the shaft of the electric motor, have the disadvantage that the rotation of the vanes coincides with the rotation of the motor shaft (the vanes cannot spin faster than the shaft, or in the opposite direction)
The blades slow down the rotation of the rotor and thus increase the losses in the motor

Embodiment Construction

[0059] figure 1 The electronic game controller 1 shown in includes a steering wheel 10 and a rotary electric motor 2 connected to the steering wheel 10 by a number of pulleys 12 and a transmission belt 11 .

[0060] Electric motor 2 comprises a rotor 3 integrated with a shaft 30 of axis xx' and a stator 4 with windings 40 mounted on a housing 41 .

[0061] Within the framework of this description, it should be considered that the rotor and stator of the motor can be switched without departing from the scope of protection of the present invention. Likewise, in an electric motor, the coil may be fixed relative to the housing and the magnet or magnets may be movable relative to the housing, and vice versa. Therefore, the reference numerals of stator and rotor may be reversed in the claims.

[0062] The case 41 includes a substantially cylindrical inner space, inside which the rotor 3 and the stator 4 are disposed; the case 41 supports the rotor 3 and the stator 4 and keeps them...

Abstract

The invention relates to a method for cooling an electric motor (2) comprising rotors (3, 4) arranged in a housing (41), said method being characterized in that it comprises a kinematically Fans (6, 7) separate from the rotors (3, 4) enable forced air circulation from the outside of the housing (41) to the inside of the housing. Likewise, external cold air is recovered at the end of the motor (2) to blow it directly through the coil (40) constituting the heat source and force it to the other end of the motor (2). Therefore, there is a uniform extraction of heat from the coil (40). Since the fans (6, 7) are kinematically separated from the rotors (3, 4), the cooling system operates independently of the rotational speed of the motor shaft.

Description

technical field [0001] The invention relates to the cooling of electric motors, especially electric motors. Background technique [0002] Motors tend to heat up when running, so add heat sinks and / or fans to the motor. [0003] However, the motors used to generate the force return effects, also known as "force return" effects, in high-end steering wheels used in video games heat up significantly, especially when the steering wheel's When the user opposes the forces generated by the motor, for example when the motor receives a stationary indication from the motor shaft (the motor shaft is stationary and thus the wheel of the steered wheel), and at the same time the user insists on turning the wheel of the steered wheel, these forces mechanically passed to the motor. More recently, the motors used to generate feedback force in high-end steering wheels for video games are brushless types. To prevent problems caused by thermal latency (ie, time to transfer internal heat to th...
