As result of changing from traditional vane motors to Huco Dynatork non-lubricated air motors for paint stirring, one UK automobile plant is saving in the region of $130,00 annual in power costs and plant renewals alone.
The customer’s original purchasing criteria for the motors were greater reliability on 24/7 operation and freedom from lubrication to avoid the possibility of contamination. However the switch to the Huco Dynatork model did much more than meet these modest needs. It also substantially cut the need for shop air as even at maximum torque, this design requires less than a quarter of the air consumed by a traditional vane motor.
This manufacturer has now installed 42 Huco Dynatork motors and these have provided a capital saving of two 600scfm compressors and an overall power saving of 152kVA annual.
The operating principle of the Huco Dynatork air motor is simple and unique. Via an integral rotary valve, air up to 6.5 bar is supplied to each of three pistons in turn. The free-floating pistons transmit torque on start-up that can be adjusted via a pressure regulator. This results in high torque at variable low speed and low noise.
The motor is ideal for use in harsh and hazardous environments and excels in constant start/stop applications under load displaying similar characteristics to those of a stepper motor. By comparison an electric motor will often burn out and a vane motor, stall out when subjected to these conditions.
These qualities make the Huco Dynatork air motor the perfect choice for paint and other liquid stirring applications across a wide spectrum of industries.
