Product Description
Brushless EC motor GEC7112A — 12/20 W, 220–240 V, 1000/1400 RPM, IP65
GEC7112A is an energy-efficient brushless EC (Electronically Commutated) motor from Hangzhou Saiwei Motor Co., Ltd., designed for refrigeration unit fans, display cases, and refrigerated furniture. Thanks to electronic commutation and insulation class H, it delivers efficiency up to 68%, quiet operation, and a service life ≥ 60,000 hours — without brushes or maintenance. The motor meets VDE, UL, EX and CE standards, making it suitable for use in explosion-hazard zones.
Main features and benefits
- Brushless EC technology: no wear parts means no maintenance and extended service life of ≥ 60,000 hours.
- High energy efficiency (up to 68%): the motor draws a maximum of 20 W with 0–12 W output power, delivering real energy savings in refrigeration equipment running 24/7.
- Quiet operation — SPL 30.6 dB @ 1300 RPM: low noise is key for commercial applications such as display cases and showcases.
- Insulation class H (180°C): the highest standard coil insulation class ensures reliability in tough thermal conditions.
- Protection rating IP65: full protection against dust and water jets — the motor can operate in humid and dirty environments.
- UL, EX, VDE, CE certifications: full compliance with European and American requirements, including approval for explosion-hazard zones (Ex).
- Motor protection by impedance and electronics: built-in electronic thermal protection eliminates overheating risk.
- Any mounting position: no orientation restrictions simplify device integration.

FAQ — frequently asked questions
What is the difference between the GEC7112A and a traditional induction motor?
The EC (brushless) GEC7112A motor has no brushes or squirrel-cage rotor — commutation is electronic. This results in efficiency up to 68% (vs. typically 25–35% for induction motors in the same power class), quieter operation, and a service life of ≥ 60,000 hours without maintenance.
Is the GEC7112A motor suitable for explosion-hazard zones?
Yes. The motor is certified EX (approved for explosion-hazard zones) and also holds VDE (REG E074), UL, CE, and CCC approvals.
In what position can the motor be mounted?
The GEC7112A motor can be mounted in any position — there are no orientation restrictions.
What supply cable is factory-installed?
The motor is factory-equipped with a CABLE 3×0.5 mm2 H03VV-F cable with a length of 1500±10 mm and black, brown, and blue wires.
Which fan blades are recommended for the GEC7112A?
According to the datasheet, the motor is compatible with blades of Ø200, Ø230, and Ø254 mm at blade angles of 22°, 26°, 28°, and 34°. The highest airflow (650 m3/h) is achieved with an Ø254/28° blade at 68% efficiency.
What is the motor noise level?
The sound pressure level is SPL 30.6 dB at 1300 RPM — a very low value, comparable to quiet office noise.
