BLDC Motor & Hall Sensor
Hub motor, phase wire, hall sensor, bearing aur motor fault ki practical jaanch.
What You Will Learn
BLDC hub motor me aam taur par mote phase wire aur chhote hall sensor wire hote hain. Sahi kram se test karne par motor aur controller ki kharabi ko alag kiya ja sakta hai.
1
BLDC Hub Motor ko Pehchanein
Motor ke main hisse
Hub motor pahiye ke beech me lagi hoti hai.
Kai BLDC motors me teen mote phase wire hote hain.
Kai motors me hall sensor ke liye chhote signal wire hote hain.
Motor me winding, magnet, rotor aur bearing jaise hisse hote hain.
Har motor me wire ka colour ek jaisa hona zaroori nahi hai.
Practical Tip:
Wire colour dekhkar hi connection tay na karein. Connector pin aur vehicle wiring bhi dekhein.
2
Phase Wire aur Motor Test
Motor winding ki basic jaanch
Motor ko controller se safe tarike se alag karein.
Teeno phase ke beech resistance ko aapas me compare karein.
Teeno reading ek-doosre ke kareeb honi chahiye, lekin exact value motor ke design par depend karti hai.
Phase wire se motor body tak anchaaha short nahi hona chahiye.
Wheel ko haath se ghumaakar bearing aur mechanical resistance dekhein.
Practical Tip:
Sirf resistance test se motor ko poori tarah sahi na maanein. Hall aur mechanical test bhi zaroori hain.
3
Hall Sensor Test
Hall signal badal raha hai ya nahi
Kai BLDC systems me hall connector me supply, ground aur teen signal wire hote hain.
Kai systems me hall supply lagbhag 5V ho sakti hai, lekin vehicle ke anusaar pushti karein.
Signal wire ko ground ke muqable measure karein.
Wheel ko dheere-dheere ghumane par hall signal ki state badal sakti hai.
Agar koi signal hamesha ek hi state par rahe to sensor, wiring, connector ya supply me problem ho sakti hai.
Practical Tip:
Hall wire ka colour aur pinout har gaadi me samaan nahi hota.
4
Motor ki Mechanical Jaanch
Har motor fault electrical nahi hota
Wheel ko haath se ghumaakar brake rubbing dekhein.
Bearing me awaaz ya zyada play jaanchein.
Motor me paani jaane ya rust ke nishan dekhein.
Motor cable ke paas wire damage dekhein.
Motor se burnt smell ya zyada heat ki shikayat ho to dhyan se jaanch karein.
Practical Tip:
Motor bhaari ghum rahi hai to controller badalne se pehle mechanical karan zaroor dekhein.
Practical Checklist
Phase connector dekhein.
Teeno phase ki reading compare karein.
Phase-to-body short jaanchein.
Hall supply aur signal jaanchein.
Bearing aur wheel movement jaanchein.
Safety First
Powered wheel test me gaadi ko safe stand par rakhein aur ghumte wheel se haath, kapde aur aujaar door rakhein.
