Food mixer JH-350A-5L-1 - Speed problem.
« on: August 26, 2015,10:20:35 »
Hi folks,

Have one in - Bearing no Maker's name, but the model number took me to China - Not too helpful, unless I want to buy a thousand.

Machine has a switched speed control at the rear, where Off is off, but in all other positions mixer runs at full speed.

Noticed a motor 'Hall effect' sensor, and a panel with a small chip, Ceramic resonator, switch and Triac.

Checked everything checkable, then resoldered them - No better. Had a feeling that no feedback from the sensor might mean top speed, but not at all sure - Was going to order the drive chip but it has no markings whatever - Unhelpful.

Any thoughts ? - Could keep 'She who must be obeyed' in obeyance - Chris.

Later - Thought to unsolder the 'Hall' sensor, and a leg fell off - probably motor vibration as leads were formed into a sort of spring to get optimum proximity to the ring magnet. Resoldered to check - OK, but a bag of 10 from China for a couple of quid inc. post for the next time.

Hi Chris,

Guess you'll have to drag out the old wooden spoon.......you know, the one your mum used to whack you  with. Doesn't seem to be the go much these days.....child brutality, I guess.

Yeah,

But as some old chap said 'It still turns' - Referring to the Mixer, of course.

Guess unlike him, our new Pope won't confine me to home 'till expiry, as is a modern guy, and where God can exist most everywhere at the same time -

Our very own Prof. Jim Al-Khalilli is currently explaining the whole biz, but seems a bit dubious about extraneous God persons, as hasn't yet noticed one amongst the Quarks and whatnots.

Could be the next discovery, as after 2000 years, need a heads up to keep the faith - Chris.
