Refrigeration applications largely depend on the capabilities of the compressor, which compresses the refrigerant, and the cooling fan that blows air through and evaporator. As energy policies and market needs change, designers look to BLDC motors for efficient, low-maintenance and quieter solutions. How Refrigerators Work Refrigerators with permanent split capacitor (PSC) single-phase induction motor compressors turn on when the temperature in the refrigerated compartment reaches a certain point. When the refrigerator reaches the set temperature, the compressor turns off. The compressor is generally noisy and draws a large starting current, which may cause a dip in voltage in the main…
Sinotech Custom Motors: Embedded Logic in Brushless DC Motors
Sinotech is happy to announce that embedded logic inside brushless DC motors is a reality. By embedding custom logic circuits inside the motor, the complexity of the system decreases along with its related costs. How Embedded Logic Works An embedded controller brushless DC motor used two donut-shaped circular boards. You could find the drivers on one or both of the boards along with three Hall Effect sensors sharing space on one of the boards if it doesn’t have a board of its own. The boards get stacked close together and use headers to connect them. Benefits for BLDC Motors Until…
China Sourcing of World Class Motor Components: BLDC Motors & More
Manufacturers who build DC gear motors, BLDC motors and other components often look to China to source components like brushes, magnets, and wound coils to keep costs low and maintain a competitive edge. While China offers attractive benefits in regards to sourcing, it’s not without risks when it comes to the engineering of a component. Outsourcing Approaches There are several ways companies can source their BLDC motor and DC gear motor components: Direct approach: When a company wishes to work directly with a Chinese factory, it must find the right factory, negotiate a price, and supervise the production for quality…

4 Medical Advances Made Possible by BLDC Motors [Infographic]
The medical world is full of devices that wouldn’t be possible – or as effective – without the brushless DC motor. This infographic explores four medical devices aided by the BLDC motor and explains why brushless DC motors are so effective. (Click to view image at full size)
Benefits of the Three-phase Brushless DC Motor Technique
Gaining popularity through various industries, the brushless DC motor is a type of synchronous motor. The permanent-magnet rotors within the BLDC motor use electronic sensors that detect the rotor’s position and a DC supply that powers an AC signal inverter. Instead of using a traditional commutator with brushes, the BLDC motor has stator windings that get electronically commutated. The lack of a traditional commutator gives the brushless DC motor several benefits over other types of motor drive architectures. These benefits include: Higher efficiency Less maintenance Ability to operate at higher speeds Smaller sizes No voltage drops across brushes (because there…
Brushless DC Motors in Medical Applications
As the medical industry advances, so does the brushless DC motor. While connected to a DC power source, BLDC motors don’t have windings attached to the rotating shaft or armature, because this is where the magnets are. While the features brushless DC motor manufacturers integrate may seem insignificant to the lay person, the consequential benefits have helped revolutionize the medical industry. Medical Applications that Use a Brushless DC Motor Breathing devices: Positive Airway Pressure (PAP) respirators that aid in the treatment of sleep apnea have BLDC motor-powered blower fans that help regulate airway pressure. Blood clot prevention: Air pumps that…
