When you are searching for a solution, you've already got a few parameters in place to help you make your decision. But do you know everything about the product you need? Let's take a look at a few parameters that may be helpful when you're considering a brushed or brushless motor. Motor Performance For each type of motor, there are different performance Levels that depend on size, voltage, flow and impedance. Brushed motors typically have higher air performance than brushless motors due to their simple design. They also only work as an open Loop system, while brushless motors can be...

Troubleshooting Blower Disassembly WARNING: Attemping to repair or diagnose a blower may void Rotron's warranty. It may also be difficult to successfully disassemble and reassemble the unit. 1. Disconnect the power leads. CAUTION: Be sure the power is disconnected before doing any work whatsoever on the unit. 2. Remove or seperate piping and/or mufflers and filters from the unit 3.Remove the cover bolts and then the cover. NOTE: Some units are equipped with seals. It is mandatory that these seals be replaced once the unit has been opened.  4. Remove the impeller bolt and washers and then remove the impeller. NOTE: Never...

In bypass motors the work is independent from the cooling air. A separate fan directly cools the motor armature and field. Usually the cooling air enters and exists through slots in the equipment housing.  Bypass blowers are electric-motor-driven blowers that segregate two paths of air: • Working Air: the path of air for performing the application’s blowing or vacuum function • Cooling Air: the path of air to cool the blower’s motor during operation. In contrast, through-flow blowers make double use of a single stream of blower airflow by channeling that flow over the motor and electronics for cooling.   ...

What's the difference between open loop control and closed loop control? Simple, it's like driving a car. When you are driving your car, you give the car more gas to go up a hill, and less gas when going down a hill. In this example, you are changing the amount of gas that is propelling the car up or down the hill. This example can be applied to open loop control in blowers. When you add resistance to the blower it will work to 100% of the voltage provided. In other words, it will max out the current Limit to provide 100%...

When it comes to selecting the right motor for your fume evacuation system, there are three main points to consider: Operating Environment, Performance Targets and Life Expectations. Without consideration of these key areas, even the best motor won’t meet your needs effectively. Let’s look at how you should think about each one and how they can impact your results.  Operating Environment  Operating environment is a critical piece of the equation because it forces you to consider where your motor is going, what kind of air you are trying to move, how you want to power it and how much room you have for it.   The first thing to keep in mind about the operating environment is the...
