does a motor with field coils need magnetisation? (Top Motor)

[Go Fleiter]

Hallo all,

  the top motor is very weak now.

No repacement US- wide  could be found.

 

One mechanic says that it´s  magnetisation may have faded.

-- Does this motor have or need magntisation at all?

-- Don´t the field coils fill in for (static?) magnetism?

 

On the other Hand: the generators too have field coils, afaik, but their polarisation is decribed in the Manual.

--Is polarisation = magnetisation?

 

Is anyone aware of a substitute motor, a 12 V variety would do.

A left and right turning field winding isn´t either needed - I can reverse the polarity via a relay.

Even the original connections to the worm gear aren´t neeeded, I can cast steel adapters myself.

Critical ist just size and power.

 

Our suppliers suggest installing a hydraulic system, but I WANT to stay with the mechanical setup.

 

Thanks for help!

Greetings from Düsseldorf.

Go

non permanent magnet...no degrading there....the field is electromagnetic....check for a variety of small items which could equate to one or more attributing factors....first off...worn brushes, second is bushing...third is armature (many need to dress and undercut the mica...dirty brush holders/wire contact here need to be tight and clean and any voltage drop at all connections from battery to motor via switch and plugs.
