The PPA range of Mining Spec Electric Motors are premium, high efficiency cast iron motors designed to withstand even the most arduous of environments. The PPA meets world market needs and standards.
PPA Series Electric motors are installed in a wide range of conditions from sub zero temperatures to tropical environments and dusty deserts. The PPA range, with its rugged cast iron enclosure, is designed to suit these harsh conditions and provide both high operational reliability and low operating costs.
All motors in the PPA range are manufactured with Class H insulation. They are designed to operate with a temperature rise of 80°C or less (Class B), and provide a thermal reserve in excess of 45°C when operating in a 40°C ambient. This ample thermal reserve means the PPA has a winding design life of 20 years.
Standard levels of enclosure protection for all PPA series motors is IP66 for both motor and terminal box. Sintered bronze porous drain plugs are fitted to the lowest point of the motor enclosure, as standard. IP66 enclosure protection means dust tight (no ingress of dusts), and protection against heavy seas (water from heavy seas or water projected in powerful jets shall not enter the enclosure in harmful quantities).
