Hicool electronic industries manufactures a range of electronically controlled ac and dc fan motors which are used mostly as instrument/appliance cooling fans. The frame of this motors are constructed of die cast aluminium, powder coated black, injection moulded and ul94v o rating non flammable thermoplastic. These ac & dc fan motors are available in a reliable brushless dc type shaded pole construction with injection moulded impeller of thermoplastic material. These ac & dc fan motors are available with salient features like precision life lubricated ball bearing system; precision oil impregnated sintered sleeve bearing system; 10 megohms minimum at 500 v dc insulation resistance; between terminal and housing 1500 v ac/1 minute for ac fans and 500 v ac/1 minute for dc fans dielectric strength; impedance protection [for ac fans] designed in that wiring will not burn out even if the rotating parts are restricted; 72 hrs locked rotor protection at rated voltage; polarity protection [for dc fans] reverse connection at rated voltage will not cause any damage; e class insulation and operating temperature/storage temperature 10°c to +70°c for sleeve bearing; 20°c to +80°c for ball bearing. The ac & dc motors can operate in 50 hz-115 v ac voltage range from 85 v to 125 v; 230 v ac voltage range from 190 v to 245 v; dc - 12 v, 24 v and 48 v ±10%.
