Mixer Grinder Mein Copper Motor Kyun Zaroori Hai?
May 2026 · SK Kutubuddin · 5 min read
Bhai, ek cheez hai jo most log ignore kar dete hain — motor ki winding. "Copper wound motor" likha hai ya "aluminium"? Yeh ₹300-₹500 ka fark nahi, yeh 3 saal vs 7 saal ka fark hai.
| Factor | Copper Motor | Aluminium Motor |
|---|---|---|
| Life Span | 5-7 saal | 2-3 saal |
| Heat Up | Kam (60-70°C) | Zyada (85-95°C) |
| Efficiency | High (90%+) | Low (75-80%) |
| Power Loss | Kam | Zyada |
| Starting Torque | Zyada (batter ke liye better) | Kam |
| Price Difference | ₹300-₹500 zyada | Sasta |
Copper Motor Kaise Kaam Karti Hai?
Motor ke andar ek coil hoti hai jo electricity ko magnetic field mein convert karti hai. Copper mein resistance kam hota hai aluminium se, isliye:
- 1.Same wattage pe zyada torque milta hai — batter grinding smooth hoti hai
- 2.Heat kam generate hoti hai — motor garam kam hoti hai, isliye OLP (overload protection) kam trip hota hai
- 3.Winding mein flexibility zyada hoti hai — vibration se damage kam hota hai
- 4.Corrosion resistance better — India ki humidity mein yeh matter karta hai
Real Test: Copper vs Aluminium
Maine dono type ke mixers ko same load pe test kiya — 1.5L idli batter, 20 min non-stop:
Copper 750W (Philips HL7756)
- • Final motor temp: 58°C
- • No OLP trip
- • Batter: Smooth, no lumps
- • Noise: Consistent
Aluminium 750W (Local Brand)
- • Final motor temp: 89°C
- • OLP tripped at 14 min
- • Batter: Some lumps remained
- • Noise: Increased after 10 min
Kaunse Brands Mein Copper Motor Milti Hai?
Philips100% copper in 750W+ models. Box pe 'copper winding' clearly mentioned.
SujataHeavy duty copper + double ball bearing. Most reliable.
BoschCopper in all TrueMixx Pro models. German engineering.
PreethiFBT motor mein copper. Zodiac series confirmed.
ButterflyMixed — Smart series mein copper, budget mein aluminium possible.
HavellsGenerally copper in 750W. Budget models check karo.
💡 Hamari Raay
Agar koi mixer "₹300 sasta" hai bina copper ke — mat lo. 2 saal baad ₹3,000 ka naya mixer lena padega. Copper motor wala ₹300-₹500 zyada lekin 5-7 saal chalega. Simple math hai.
