A dyno or dynamometer is a device used to measure the rotational speed (rpm) and torque of a moving motor or engine simultaneously to calculate the instantaneous power. Most dynamometers use power absorbers like an electric motor, a water brake, or an eddy current. These absorbers apply a specific load to the motor or engine, estimating the resultant torque with a load cell or strain gauge. In contrast, inertia dynamometers use a flywheel mass (inertia) instead of power absorbers to measure the acceleration rate to estimate the resultant torque. The power is then calculated using the resultant torque. The power calculated...

The MINIPRO® Electric Dyno offers many advantages when it comes to design and tuning electric motors. It's convenient for many markets, robots, radio control industry, medical, power equipment, and any small-sized motor applications. It's small in size and economic to fit the budget of many customers. This is an Inertia type Dyno, meaning it tested motor accelerates a flywheel to measure both power and torque. That means, repeated test results one after another. It's also capable of testing any type of small motor by selecting the right configuration of pulley, motor holder, and flywheel.  The software is  easy to use, and no previous technical...

When you want to buy a new brushless motor for your r/c car, robot, or mechanical applications, have you ever been confused why the motors are interpreted by Turns (T) or by Kv rating? Today we are going to explain some basic information about Turns and Kv rating. What does Kv tell us? Well, it is related to the power out from a motor. Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor...
