How to easily repair all types of (BRAUN MULTIMIX GRINDER)?

How to easily repair all types of (BRAUN MULTIMIX GRINDER)?

Note:Motor should be only D.C

Q1- How you will know that your motor is D.C?
* It willcontain two magnets one is north pole and other one is south pole.
* A.C motors usually consist of Armature and field winding's in it.
* If your motor is A.C these method won't work for you.

Q2- How to repair Braun Machine?
Ans - 
* You will need 4 diodes              
* Diode looks like this in the picture below: ↓↓↓↓↓↓↓↓

Diode

* Four diodes should be connected in this direction as the diagram Below:
* For reference see above diagram with its symbol.
* I connected Multi-meter to show its working principle you have to connect its D.C wire to its D.C Motor

"Especially Braun's Mixer D.C Motor"

Q3- If we are connecting in this direction what will be the output voltage?
Ans -
Through this Bridge Rectifier Connection
Output Voltage will be (Input = Output)
For Example:
If Input A.C is (230v/120v/12v)= Output will be D.C (230v/120v/12/v)

Q4- After making connection how to control speed?
Ans -
You can Control Speed through regulator or dimmer used for fan speed control
Note - Properly connect load wire to input source (A.C supply) and Controller Wire to Bridge Connection as shown in diagrams given above

Q5- Where we will get these diodes?
Ans-
These diodes are easily available at old chargers or at stores usually this method is practiced on chargers and voltage is regulated via transformers
