Nikola Tesla  a Serbian American inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern AC alternating current electricity supply system

2. Edison DC and Tesla AC Combined !!!

3. Simple Power Savings Control Frequency & Volts

4. Motor Life Time Cost Example
The purchase price of a motor represents only a tiny fraction of the life time costs of the motor.
e.g. 15 HP 4 Pole Standard Motor, typical price approx. $ 450
Assuming
Typical Industrial Electrical Cost of 0.11$ / kWh
Motor operates
12 Hours Per Day
6 Days Per Week
48 Weeks Per Year
Motor Efficiency 92%
Over a 10 Year operating period, the electricity used will be :-
(11kW x 12 Hours x 6 Days x 48 Weeks x 10 Years) / 92% Efficiency = kWh!
... At a cost of $45,454.00!
The purchase price represents less than 1% of this cost!
Briefly cover the main high-level points of what a VFD is for those only marginally familiar
Give enough information to get the uninformed and the marginally informed up to speed
Keep it brief enough to keep from losing the interest of those who are knowledgeable
