Significant Energy Savings: Reduces energy consumption by 15-30% compared to equivalent induction motors, substantially lowering operational costs
Eco-Certified Performance: Complies with international premium efficiency standards, supporting enterprises in achieving sustainable production goals
Modular Architecture: Interchangeable mounting flanges within the same frame size, flexibly adapting to diverse equipment layout requirements
Space-Saving Design: One frame size smaller than equivalent induction motors, conserving valuable installation space
Seamless Replacement: Identical mounting dimensions to standard induction motors, enabling direct upgrades without mechanical modifications
As shown in the figure, taking the IE5-1.5kW-1500rpm-416 motor as an example, its rated operating point efficiency reaches 90.8%, significantly exceeding the national Grade 1 energy efficiency standards and achieving the exploration criteria of IE6 energy efficiency. Moreover, the maximum efficiency surpasses 91%. In the efficiency Map diagram, within the speed range of 200 to 2000 rpm, the proportion of high-efficiency areas is notably large, demonstrating excellent full-condition energy efficiency characteristics.
Remarks：
1）For the power range of 0.55 kW to 22 kW (IC411): When using a gearbox with a variable frequency drive for long-term operation, the running frequency should not be lower than 25Hz, adopting a self-cooling method. This replaces the traditional solution of 'standard asynchronous motor + variable frequency drive'.
2）For the power range of 0.55 kW to 22 kW (IC416):
Capable of meeting all operating conditions, this solution employs a forced cooling fan design that directly replaces the traditional "variable frequency motor + inverter" configuration.
| Cooling Methods | IC411 | IC416 |
| Explanation | Totally Enclosed Self-Ventilated Cooling | Forced Ventilation Cooling |
| Cooling Principle | The fan is coaxial with the motor rotor, and its speed changes with the motor's rotational speed. Cooling efficiency decreases as the motor slows down. | An independent power supply drives a dedicated cooling fan, ensuring stable cooling performance regardless of the motor's rotational speed. |
| Wiring Method | Single set of motor leads (no separate wiring for the fan). | Two sets of motor leads: one for the main motor and another for the cooling fan. |
| Application Scenarios | Ideal for variable torque loads where power demand decreases with motor speed (e.g., centrifugal pumps, fans). | Suited for constant torque applications requiring high power output at low speeds (e.g., conveyors, crushers). |
