OUR ACHIEVEMENT

In 2015, Metropolitan have conducted effective coordination and cooperation with KEPPE MOTOR and developed an more energy efficient motor. The Keppe Motor uses the principle of Electromechanical resonance to achieve maximum efficiency.

In oscillatory systems, the state of resonance is achieved when the minimum energy input causes maximum efficiency. Similarly to a resonant pendulum that swings back and forth in maximum amplitude due to a ideal periodic impulse, the Keppe Motor reaches maximum output for a determined electric energy impulse.

The outcome of this principle includes electromechanical resonance expressed by a combination of factors that involve inertia, EMF, back-EMF and feedback energy as active inputs to the efficiency of electric motors.

Advantages of the KEPPE MOTOR:

• Single-phase RC motors at competitive costs with higher efficiencies than equivalent BLDC and PMSM motors.
• Introduces a new line of single-phase coreless stators and ceramic magnets up to 1 CV with efficiency above 90% for single-phase AC grid supply.
• Increasing Turbo effect with higher speeds.
• No cogging for coreless configurations: perfectly silent single and three-phase motors.
• Very simple to manufacture.
• Less heat produced.
•  Less noise for iron core configurations than similar BLDCs.
• Single-phase BLRC motors more efficient than similar three-phase BLDCs and PMSMs.
• Room for development of three-phase Resonant Current microcontrollers embarking FOC algorithms to account for the EMTS feature applied in 3-phase BLRCs aiming at efficiency and performance improvement.
• Worldwide patent application with certificate already granted in the United State, Russia, China, Hong Kong, Canada and Mexico.

Metropolitan and Keppe Motor are the finalists of the 2015-2016 Global Leap Awards.

The Global LEAP Awards is an international competition to identify and promote the world’s best off-grid appliances.

The 2015-2016 round of competitions will identify super-efficient, high quality off-grid fans.

All Global LEAP Awards nominations are tested according to internationally-accepted laboratory test methodologies to confirm their energy performance, durability, and reliability, and are also evaluated by a panel of off-grid market experts. Winners will be identified through a combination of expert evaluation and energy and cost based quantitative assessments.

Previous Global LEAP Awards Winners and Finalists have experienced sales and investment opportunities. 

Global LEAP Award Winners and Finalists benefit in the following ways:

• Recognition at the 7th Clean Energy Ministerial in June 2016, a major global meeting of energy ministers
• Use of the Global LEAP Awards brand to differentiate your products to investors, development organisations, institutional customers, and others.
• Significant exposure through a multi-faceted publicity and business-to- business marketing campaign,
• Participation in a new Global LEAP program incentivising large-scale procurement and distribution of Winner and Finalist products in  key off-grid markets.
