Electricity
Series DC motors connection
Two brushed electric motor connected in series for parallel shaft working.
Two schematics for connecting motors
Three phases AC electric motor
The motor with an angular position sensor
The sensor is use for variable speed application
Electronics power stage
The power MOS-FET are protected with fast recovery diodes
Automotive alternator
- The P1, P2 and P3 slots are for power
- The D+ is the supply of the voltage regulator for the rotor coil
- The D- is the negative supply of the regulator
- The DF is the regulated voltage
Angular position sensor
- Schematics with a magnet and two magnetic sensors
- I choose the Philips KMZ 10 B magneto resistors bridges and a Alnico 3.2 x 3.2 x 19.1 mm magnet
H1 signal, 60 mVpp - 40 ms
Only the bottom sensor is used
Speed control blocs schematics
