Understanding Brushless DC Motor Efficiencies
Brushless motors are a hot commodity in the automotive industry, as well as for robotic and medical applications. By knowing the differences that BLDC motors and brush DC motors offer, you can make an educated decision about the best type for your application. Brush DC Motor Efficiencies Cost: Brushed DC motors are generally less expensive than their brushless counterparts. Simple control: The motors have a two-wire control and need little to no control in fixed-speed designs. Magnet placement: In brushless motors, the magnets are in the rotor. This means that connections, a commutator and brushes aren’t needed because of the…
Stepper Motors vs. BLDC Motors: Differences & Uses
When you need a motor for an application, you may not know if a brushless DC motor or stepper motor is best. In principle, both types are permanent-magnet synchronous motors. The difference is in their specific characteristics and mode of operation. BLDC Motors Brushless DC motors are highly reliable and efficient, and have a high power-to-volume ratio. This high-power motor can deliver large amounts of torque over a range of speeds. BLDC motors are electronically commutated constantly changing the waveforms being delivered to a wound stator. Brushless motors with an outer rotor tend to operate at lower speeds and have…
DIY Home Improvement: Powering Up with BLDC Motors [Infographic]
Thanks to brushless DC motors, tackling home improvement projects is simpler than ever. On average, over half of the adults in the U.S. tackle a DIY project each year. Because of BLDC motors, power tools have longer run times on a single battery charge, are more compact, lighter in weight, more powerful, smarter and last longer. This infographic explores trends in home improvement projects across America, the power tools used and the evolution of brushless DC motors. When you partner with Sinotech for your brushless DC motor needs you’ll reap the benefits of working with a dedicated, knowledgeable company with…
Understanding Refrigeration Applications & BLDC Motor Control
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…
Get Optimized Motor Performance from Advanced Motors & BLDC Motor Controllers
Brushless DC motor (BLDC) systems are the most preferred systems for the simple reason that they are cost-effective. The cost, which includes maintenance, downtime and costs related to energy requirements, is lower for these systems as compared to their brush type counterparts. The performance of any motor depends on the performance of its two components namely, motor and controller. This is particularly true for BLDC motors, in which BLDC motor controllers play a crucial part in determining its performance. Sinotech’s Brushless DC Motor Controller Design Sinotech’s aim is to provide clients with solutions that are tailor made for their requirements…
Trends in Energy-efficient Brushless DC Motor Controller Design
Energy efficiency has become a vital judging criterion for products, from automotive machinery to home appliances. As a result, this aspect is considered in the development processes now, more than ever before. Although there is no absolute sure shot method to achieve this kind of efficiency, we present here the trends that have been noticed in recent past. Sensor-less Brushless DC Motors The use of sensor-less controls in brushless DC motors presents an excellent option, which is capable of delivering extremely high component power. However, there are positives and negatives of using this technology. While the use of sensor-less control…
