Do you know that changing your v-belt can reduce your electrical bill?
Today’s industries spend about 70% of the energy running electrical motor systems, so the obvious thing to do will be change them to new energy-efficient units, right?. Well, the answer is: not always; as this will be a high costs and long down time on production.
A high efficiency unit or system is one that has the ability of transmitting the most power with less energy loss. What we see in the industry is that the most common form of energy loss is heat, which is generated by friction.
So, we are getting to the point. As a belt operates, it goes in a cycle from the pulleys to the straight section and again to the pulleys and in the process, friction is generated and produces heat. Because regular V Belts do not bend easily, they produce a higher amount of heat if compared with cogged belts or timing belts, which will bend easily, generating less friction, traduced in less heat, meaning less energy loss.
V belts perform at 93% of efficiency if proper maintained while timing belts perform at 98% of efficiency. Let’s traduce that to money to make it more interesting. Let’s assume we have a 10HP electric motor that runs 7500 hours per year and the cost of energy is $0.0696 per KWh (Average price for Electricity in USA Industrial sector January 2014).
| If we are using v-belt drive, the efficiency is 93% | If we are using synchronous drive, the efficiency is 98% |
| KW Consumed=(.746*10)/.93 | KW consumed=(0.746*10)/0.98 |
| KW Consumed=8.02 | KW consumed=7.31 |
| Energy Cost=7500*8.02*.0696 | Energy Cost=7500*7.31*.0696 |
| Energy Cost=$ 4,186.44 | Energy Cost=$ 3,815.82 |
SAVINGS OF $370.62 PER YEAR just changing one drive from V-belt to synchronous

*Keep in mind that synchronous drives are not the correct choice for all applications.
