Ceramic heater

Deserted ceramic heater was repaired with connecting power supply wiring and the air was cleaned , no thermal fuse was destructed and heater was alive.

Equipped AC motor is called as skeleton motor with the advantage of cheap, simple and small.
Two phases are created by two turning stout copper wiring around the outer pole, especially because of making shadow phase, this type of motor is called as "Kumatori Motor" in Japan.
"Kumatori" is the very special way of make up of the face in Japanese traditional stage arts "Kabuki", zebra pattern of shadow making way. This kid of pole induction motor is mainly used for family fan, the difficulty to control speed is cleared by recent sophisticated circuitry designing methods utilizing an inverter.

Supporting main plane bronze bush bearing of the motor was lubricated with extreme pressure additive containing grease, Microflon. Also rotary switch was lubricated on mechanical cam motion portions. The heavier movement of the rotary switch has repaired. Now no overview and mechanical problems is observed on this small but effective ceramic fan heater.

This additional heating system will play a great part of working place in my garage this winter.
