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 = 413217.4 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
