Energy Savings by Upgrading to IE3/IE4 Motors
Energy Savings by Upgrading to IE3/IE4 Motors
Energy efficiency has become a key priority across industries. With electricity costs rising and sustainability goals tightening, upgrading from IE1 or IE2 motors to IE3 or IE4 can result in substantial long-term savings. CG Power offers a full range of high-efficiency motors designed to deliver superior performance while reducing operational costs.
1. What Are IE Efficiency Classes?
The International Electrotechnical Commission (IEC 60034-30) defines efficiency standards for motors. These are classified as:
- IE1: Standard Efficiency
- IE2: High Efficiency
- IE3: Premium Efficiency
- IE4: Super Premium Efficiency
2. Efficiency Comparison
| Motor Power | IE1 Efficiency | IE2 Efficiency | IE3 Efficiency | IE4 Efficiency |
|---|---|---|---|---|
| 1.5 kW | 77.0% | 81.5% | 84.1% | 86.5% |
| 7.5 kW | 87.0% | 88.5% | 90.4% | 92.0% |
| 15 kW | 88.0% | 90.0% | 91.8% | 93.0% |
| 37 kW | 91.0% | 92.3% | 93.6% | 94.4% |
3. Why Upgrade to IE3 or IE4?
- Reduced Power Consumption: Higher efficiency means less electrical loss and lower running costs.
- Lower Heat Generation: Enhances insulation life and motor reliability.
- Reduced Carbon Footprint: Each upgrade contributes to sustainability targets and regulatory compliance.
- Faster Payback: Despite higher upfront cost, savings on energy bills recover the investment quickly.
4. Typical Energy Savings Example
Replacing a 15 kW IE1 motor with an IE3 motor operating 6000 hours per year can save approximately 6,000–7,000 kWh annually. At ₹8 per kWh, this translates to ₹48,000–₹56,000 savings per motor per year.
