Designed for 40,000 h service, Ametek’s DurA-Tek 12/24 V brushless DC motors offer compact and rugged solutions for demanding high duty cycle applications in heavy-duty transit buses and construction and off-highway vehicles. Their 76,2 mm outside motor diameter and standard 2-wire electrical hookup allows them replace similarly sized brush-commutated DC versions and deliver relatively higher performance and extended life. The motors achieve continuous torques from 0.13 to 0.39 Nm and speeds from 2,927 to 4,400 rpm. They resist water spray, rain, humidity, salt, fog, shock, and vibration associated with harsh environments. Integrated drive electronics promote enhanced motor controllability in a smaller, lighter package. The “smart” onboard motor controls and advanced electronic design deliver such key features as multi-speed operation, over-current control, locked-rotor protection, reverse polarity protection, transient over-voltage protection, and over-temperature shutoff.
