Drive selection


The ATV630 is a drive aimed at fluid movement (pump and fan) applications and therefore has the same properties and performance that we would normally associate with a variable torque drive

The ATV930 is aimed at material handling and artificial lift applications, traditionally ones that we call constant torque, so has similar performance to those drives. One thing to note is that ATV930 is available in both normal duty and heavy duty options with 120% and 150% overload capacity respectively. This differs from the ATV71 which was essentially only available as Heavy duty version.
