You hiring concerns a particularly space-saving way of accommodating the Ringkondenaatoron in the motor housing. Keuerungsgemäaa If the capacitor is arranged in the bearing shield, which is not penetrated by the shaft, the end wall of the shield is so drawn in, there is a ring-shaped space to accommodate the capacitor and, in sum, another one lying in the middle of the bottom a tree that opens on the outside arises, and in this tree that , Terminal board of the motor housed.

An exemplary embodiment of the hiring is given below of the drawing, which shows a longitudinal section duroh the capacitor motor.

The housing X removes the stator 2 on the front bearing shell 3 and the rear end shield 4 sohliesaen. the housing. the Shaft 5 carries the rotor 6 and is mounted in the ball bearings 7 and 8. The ring-shaped capacitor 9, also shown in section, is by means of threaded pins 10 and nuts attached to the end shield 4. The threaded pins 10 tdnd with the Capacitor housing 9, for example, connected by soldered connections with metallic conductors. This cavity 12 doesn’t open onto the terminal board 13. The capacitor lines 14 and 15 are led through DurohbrUche 16 to the terminal board 13 · With the cover 17 »the one opening for the Note connection cable 18 has »1st the cavity 12 is covered ·

With this execution of the Kondenaator-Kotors will continue achieved the following advantages.

The cable connection from the capacitor to the terminal board of the motor is also protected inside the motor. This is particularly important because it carries a much higher voltage than the operating voltage of the motor and damage to the capacitor cable is therefore very dangerous. In addition, the bearing plate 4 mounted with the capacitor 9 can be bonti-rt normally. So, like a normal bearing plate, placed on the motor housing 1, it can accommodate the rotor shaft 5 with the ball bearing.Due to the coordinated construction of the capacitor and the rear bearing oil, the construction of this capacitor motor is not larger than all ζ · $ · Centrifugal so &lter-b'otor of the same power.
