Ampflow A28-150-G 3" 24V Motor and Gearbox

The A28-150-G uses the A28-150 24V 3.0hp motor but is also fitted with a 8.3:1 reduction chain drive gearbox.

These strong gearboxes give a huge amount of torque which is ideal for heavy duty robotics, motorised vehicles and automation applications.

The gearboxes are made using a three-piece CNC machined aluminium case. The mechanism comprises six sprockets, three roller chains and five bearings. The final sprocket and output shaft are made from a single piece of steel to maximise strength.

The motor and gearbox assembly can be mounted on a plate up to 10mm thick using the four 1/4-20 thread screws supplied.
