The BLV Series is one of two DC-input brushless motor speed control systems we offer. While a brushless motor with hall-effect sensor feedback provides constant torque, wide speed range, and speed regulation, the BLV driver offers unique functions designed for mobile robots, such as low battery operation and ramp operation.

When a voltage is applied to an AC induction motor, it runs at a certain speed. Variable speed requirements for AC induction motors are typically fulfilled by a 3-phase motor and an inverter, or VFD. This blog post introduces another option.

The differences in single-phase and three-phase AC induction motors don't stop with the input power supply. There are a few things you need to know when using three-phase AC induction motors in an instantaneous forward/reverse operation.

Knowing how to use a product properly can make a huge difference in its performance and life. For example, knowing how to maintain cast iron pans properly can make them last longer. With electric motors, understanding the factors that affect motor life is the first step to extending life and decreasing costs in the long run.

I will never forget my first engineering project involving motors. I built a small elevator for a science class back in elementary school. Of course, it worked great during the testing phase, but it failed to perform when it counted.

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?

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?

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.

Now that we understand the calculations behind load torque and load inertia, we're two steps 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.

Other than torque or speed, another factor should be considered when sizing motors.
