ATT DL Series compromises of capacitor start and run, single phase, squirrel cage motors in Aluminium die cast frame. A removable foot mount is integrated in DL Series motors as an additional feature to enhance its mounting versatility. It can be used for general purpose applications in machines as well as in areas which have weight limits due to lighter aluminium frames. They are especially suitable for family workshops where only single-phase current supply is available.

ATT DL Series motors are enhanced with an electronic or manual centrifugal switch to provide better performance during operation. When the motor approaches its normal operating speed, the centrifugal switch disconnects the starting winding from the power source; the motor then continues operating solely using its running winding. Motors using such a centrifugal switch make a distinct clicking noise when starting and stopping as the centrifugal switch opens and closes.

These single phase motors are perfect for high starting torque applications such as air compressors.
