The stator creates a magnetic field which in turn will rotate the rotor consisting of magnets to power the machinery. Brushed motors on the other hand, use a series of carbon / precious metal brushes to transfer
What is the purpose of the deflection plates in the oscilloscope CRT? Research and describe in details one device, vehicle, etc. that works on one or several capacitors. a. What are the advantages/disadvantages for using capacitors vs. chemical batteries. b. Has any a ...
Additional differences include preparation of specimens before being placed in the vacuum chamber, the use of coiled electromagnets instead of glass lenses, the use of a thermionic gun as an electron source and the image or electron micrograph is viewed on a screen rather than an eyepiece. ...
A different category of magnets are electromagnets, which are essentially magnets that can be turned on and off. The most common electromagnet that is used in various industrial applications is a solenoid. A solenoid is a series of current loops, which result in a uniform field in the ...
With the electromagnets on the stator, they are very easy to cool. You can have a lot of electromagnets on the stator for more precise control. The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the...
The electric flux is governed by an equation Φ=E→⋅A→=EAcosθ where, Φis the electric flux Eis the electric field Ais the area θis the angle between the electric field and the normal vector of the area. Remind that the electric flux is a scalar quantity. ...
There are alsoactive crossovers. Active crossovers are electronic devices that pick out the different frequency ranges in an audio signal before it goes on to the amplifier (you use an amplifier circuit for each driver). They have several advantages over passive crossovers, the main one being tha...
What are the advantages and disadvantages of an HDD? Hard disk drives (HDDs) remain a cornerstone in digital storage, valued for their cost-effectiveness and expansive capacities. However, alongside their reliability and compatibility, HDDs face challenges such as speed limitations and mechanical vulner...
This type of motor is programmed to maintain the same speed regardless of static pressure in the HVAC system. If airflow is restricted, it will increase its torque to maintain the same speed. Constant speed ECMs are typically used for AC condenser fans. Advantages of an ECM Motor Energy ...
From a simple boot up to browsing the Internet, everything is possible due to the presence of storage devices like hard disk drives or SSDs. Each storage device has its own advantages and disadvantages. This blog discusses what storage devices are, the types of storage devices over the ...
