The viscosity change in liquids can vary the torque required for mixing. For AC asynchronous motors such as AC induction motors, the rated speed is affected by load torque fluctuations, which may cause inconsistency in the final product. Is there a better motor for the job?

Minimizing the Effect of Load Fluctuations for Mixers
Topics: Speed Control, VIDEOS, BLDC Motors, Gearheads, Washdown, Application Examples
Control Basics: The Difference Between Sink and Source Logic
For someone who has never had experience wiring I/O for motion control, it can be scary the first time. If devices are not wired correctly, it can cause a range of issues from a motor simply not doing what's expected to irreversible product damage. I still get that nervous feeling before I press the START button on a demo. Murphy's Law, anyone?

Motor Sizing Basics Part 4 - How to Calculate Radial Load and Axial Load
Besides load torque, acceleration torque, speed, and load inertia, overlooking certain sizing parameters during the motor sizing process can literally make or break your machine.

Motor Sizing Basics Part 3: How to Calculate Speed, Acceleration Torque, and RMS Torque
Now that we understand the calculations behind load torque and load inertia, we're a little closer to motor selection. You might be wondering why I separated load torque and acceleration torque calculations. That's because in order to calculate for acceleration torque, load inertia and speed must be calculated first.

Motor Sizing Basics Part 1: How to Calculate Load Torque
Proper sizing of a motor requires that 3 criteria must be met: torque, load inertia, and speed. For the first part of this Motor Sizing Basics series, I will be explaining what load torque is, how to calculate it for specific application examples, and how it fits into the torque requirement for the application.

Eliminate Motor Speed Fluctuations Caused By Input Voltage or Load Variance
An AC motor can be simple to use, but its speed changes according to the size of the load or amount of voltage supplied. For an application where keeping a uniform speed is important, there is another type of motor that can improve performance.

Improve Motor Performance With Redesigned Compact BLDC Drivers
The BLH Series compact BLDC motors and drivers have been around for a long time, and there is a good reason. Customers seem to favor the combination of a highly efficient, compact motor and a light weight board type driver that is easy to use. Having a high torque, flat style hollow shaft gearhead as an option also helps in increasing torque as well as minimizing footprint.

Better Motor Alternatives for Variable Speed Pumps (VIDEO)
What motors do you use for pumps? For variable speed pump applications that typically use 3-phase AC induction motors with variable frequency drives (VFDs), there is another type of motor that can transfer fluids more consistently and help reduce footprint.
