DE4417326A1 - Electric motor with double-action solenoid magnets - Google Patents

Abstract

The electromotor has double-action magnets. The arrangement includes two outer U-shaped magnets with constant polarisation. These lie on either side of a movable inner iron core magnet. The uniform pole alternation determines the timing of the oscillation movement. Alternatively, the outer magnets can be movable and the inner magnet can be stationary. In the courses of the pole alternation of the inner or outer magnets, the oscillating movement may have a variable frequency and stroke.

Description

The device according to the invention relates to a double acting solenoid equipped electric motor, preferably with two constantly polarized external magnets (permanent magnets) and one pole changing inner iron core magnet.

AC 50 Hz is used as the energy source.

In the known electric motors, oscillating movements are involved eccentric or generated by magnets against spring.

These solutions have the disadvantage that the energy conversion by the Implementation of circular to oscillating movements and others on the one hand, the attractive magnetic force against the spring, to a reduction the power transmission leads.

The advantages of the device according to the invention are a better energy Yield and thus a higher efficiency of the engine.

Because with this solution principle also a powerful movement in two Directions achieved and covered a relatively large stroke is a more effective energy turnover and labor input. The engine is therefore particularly suitable for such areas of application, where oscillating and / or intermittent movements are required. (Electro hammers or similar)

In the following embodiment and the drawing are the preferred Variants of the device invention described and illustrated:

Fig. 1 shows the basic structure consisting of three magnets in cycle 1, movable inner magnet I is attracted by opposite polarity from the right outer magnet and at the same time repelled by the left.

Fig. 2 shows the basic structure analogous to Fig. 1 in cycle 2, movable inner magnet I is now attracted by the polarity reversal from the left outer magnet and at the same time repelled by the right. This principle is

Fig. 3 accordingly, also vice versa, with fixed internal magnets constantly po larized, and movable, pole-changing external magnets realizable bar.

The process of changing the poles of the inner or outer magnets determines so the rhythm of the oscillating movement and is therefore in frequency and adjustable in the stroke.
