Hi All
I am asking this question as a mechanical engineer, so please bare this in mind if you have the time to post a reply...
I have a basic DIY type cement mixer that has given up today. It is a AC 230V model with the most basic of drive setups (pulley and drive belt attached to the motor shaft).
I set everything up today to mix some concrete and turned the mixer on. Without the barrel fitted (no load on the output shaft) the motor turned no problem, then after around 20 seconds the motor slowed down and stopped completely over a period of around 10 seconds. I turned it off and noticed a smell, the familiar smell of electrical equipment going 'poof'.
Having then removed the protective cover from the motor to investigate it became apparent that the motor was too hot to touch with my bare hand. The motor will start when it has cooled down, then stops running as described above.
I have removed the motor from the machine in order to fit a replacement but have some questions about the existing motor before I splash out on a new one...
1. Why would a motor overheat so quickly?
2. Is there potential for a cheap/simple repair to the existing motor?
I am genuinely interested to understand the technicalities of such devices.
I've attached a picture of the rating sticker.
Much respect
Koth
