Brushless DC Motor Technology & the HVAC Industry

Sinotech    April 14, 2014

Electric motors account for up to 50 percent of the energy used in U.S. commercial buildings, 60 percent of the energy used in U.S. industrial buildings and about 45 percent of the total global energy consumption. To help curb energy use, more industries are integrating brushless DC motors into their systems, particularly those in the HVAC industry. What is a BLDC Motor? There are two basic types of motors: those with brushes and those without. BLDC, or brushless, motors don’t have carbon brushes or commutators, which can cause premature wear and tear. Instead, they use a controller board to adjust…

Understanding Brushless DC Motor Efficiencies

Sinotech    January 13, 2014

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

Sinotech    December 16, 2013

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…
