Brushless DC Motors Controller
Outer Reef Technologies
Brushless DC (BLDC) motors are electronically commutated and are quickly growing in popularity owing to their improved torque-to-weight ratio and superior electrical efficiency. They perform noticeably better than mechanically commutated, brushed motors because of these improvements.
They are categorized as permanent magnet synchronous machines or PMSMs. Unlike PMSM motors that demonstrate sinusoidal back EMF because of distributed stator windings, the concentration of stator windings in BLDC motors demonstrates a trapezoidal back EMF.
This means that brushless DC motor control systems commonly use trapezoidal control. Field-oriented control (FOC) is also used in some BLDC motor control systems, whereas a typical PMSM motor will only use a field-oriented motor controller.
Trapezoidal control in BLDC motor control systems is less complex than FOC because it energizes just two phases at any given moment. Torque control in trapezoidal brushless DC motor control systems is operated by a single PID controller.
Moreover, BLDC motor control systems do not require coordinate transformation, unlike typical field-oriented control that uses Park and Clarke transforms for this purpose.
Here is how the engineers at Outer Reef Technologies design BLDC motor control systems using trapezoidal methods for improved efficiency, reliability, and control.
This trapezoidal control design in BLDC motor control systems provides immense advantages in operations.
BLDC motors offer high torque, wide speed range, and energy efficiency in a space-saving design, and these result in the majority of its advantages when compared to other motors. They are widely popular because they save time, cost, and space while enhancing performance, reliability, and efficiency.
Outer Reef Technologies offers some of the best brushless DC motor control systems and engineering expertise to its customers.

Product development services include but are not limited to; medical device development, robotics, electronics, firmware, software, mechanical design. Our team can help from initial concept through product launch and anywhere in-between.
Our team excels in understanding regulatory requirements for developing a thorough and cost effective plan, to meet your specific needs. We can assist in developing a quality management system for your company, guiding products through regulatory testing, and formal submissions such as FDA/EU/CE.
As we have many years of experience in new product development and prototypes we have transitioned over the years into also supporting our clients from production equivalent builds used for verification and validation to full production line support of complex electro-mechanical and optical assemblies.
The rotor requires the electromagnetic poles to switch to spin a full 360 degrees. This is where the brushes come in. As the rotor spins, the brushes make contact with the stator, and this switches the poles, allowing the rotor to achieve a complete 360 degrees spin.
A brushless DC motor is a brushed DC motor but turned inside out. Hence, a BLDC motor has a permanent magnetic rotor and a spinning electromagnetic stator. This eliminates the need for any brushes to flip the electromagnetic poles.
A computerized BLDC motor control system simply energizes the stator to make complete 360-degree spins.
