This series motors with box type steel structure, can be adjusted its speed using high voltage inverter; Forced cooling structure for the cooler or protective cover, ensure the cooling effect of motor under low frequency operation; Insulation structure for bearing, reduce the damage from shaft current and improve the life of bearing. This series motors have characteristics of high reliability, wide speed range, high precision, beautiful appearance, low noise, little vibration, and can be applied to fan, pump, compressor, mining machinery, engineering machinery installed in power plant, steel mill, mine and so on.
This series motors with box type steel structure, can be ajusted its speed using high voltage inverter; Forced cooling structure for the cooler or protective cover, ensure the cooling effect of motor under low frequency operation; Sliding bearing is installed and forced lubricated by lubricating station. When the power is more than 2000kW, according to the requirement of customer, another terminal box can be installed to pick up the neutral point of winding.
