| Abstract: | High-performance rare-earth permanent magnet synchronous motor is a new type of energy-saving equipment with high power factor and low working current.A good result in power saving of flotation machine has been brought since replacing 80 JO_2 motors of low-performance by the energy-saving motor.One hour run of a permanent synchronous motor results in energy saving of 1.962kW·h. Annual saving of power cost is 6992 Yuan RMB and investment payoff period is about 7.5 months. |
