What is the difference between Variable Torque and Constant Torque . . . Constant torque loads cause motors to draw relatively high current at low speeds when compared to variable torque applications This is why the same size device may have a lower HP rating for Constant Torque applications
Compressor Operating Conditions Loading#19 - Wood Compressor operating conditions can change the torque effort characteristics significantly Therefore, specify all operating conditions and ensure that analysts take them into account
Constant torque vs variable torque motors Constant torque or variable torque – The answer depends on the application Inverter duty motors typically have both constant torque and variable torque capabilities
What is the difference between the Variable Torque and the Constant . . . Constant Torque uses a linear relationship of torque and speed Variable torque is used in fan and pump applications The overload rating for variable torque is 120% for 60 seconds Constant torque has an overload rating of 150% for 60 seconds and 200% for 3 seconds
3 Types of Loads (Constant Torque Constant Power Variable Torque) Variable torque loads require much lower torque at low speeds than at high speeds The torque required varies as the square of the speed and the horsepower required varies as the cube of the speed
What sets Variable Torque and Constant Torque apart from each other? Variable Torque loads are electrical loads that start up under no external resistance or load They initiate their operation smoothly and gradually, without significant resistance Examples of Variable Torque loads include fans and clean water (centrifugal) pumps
Do I Need Variable Torque or Constant Torque? - Wolf Automation Constant torque, variable torque, heavy duty, normal duty… what does it all mean? As a large, stocking distributor for variable frequency drives (VFD), this question comes up a lot This blog will help you determine what each means and steer you in the right direction for what you need
