Last week we had a real veteran in our workshop –
A Franz Kessler motor, 80 kW, after 25 years of service in a custom Waldrich Coburg machine, modified for grinding.
The manufacturer’s diagnosis: “Beyond repair.”
Sent to us via express – winding failure due to overload.
Sounds manageable.
If it weren’t for the living culture inside the cooling jacket…
Yes, really – bioactivity inside a spindle motor.
A clear result of years of missed maintenance.
The cooling jacket had to be turned down – only then did the full extent of the damage become visible.
A new cooling jacket? Manufactured within 48 hours.
✅ The good news:
We saved it – the motor is running again.
Our tip:
Regular maintenance prevents nasty surprises.
Talk to us – we’ll take care of it.
