Quick review of Brushed and Brushless DC motors

 

Brushless DC (BLDC) Motors are getting more popular than Brushed Motors. DALA S1 BLDC Motor Controller.

 

While ''Brushed'' DC motors use brushes and a comutor for controlling the movement of motor's rotator, the Brushess DC Motors don't utillize brushes. BLDC Motor movement is controlled by designed drive signals. The BLDC motors offer improved reliability, longer life, more compact size and lower weight. So BLDC motors become more popular in applications where efficient is critically concerned. Thus, BLDC motor is considered to be a high-performance motor capable of providing large amounts of torque over a wide speed range.

 

The DALA S1 BLDC motor controller supports hall-effect sensor for detecting the position of the motor's rotor with respect to the motor's stator. It provides true 2 minute Arms ratings, not short duration ‘boost’ ratings.

 

More features of S1:

Support regenerate break, SOC algorithm, magnetic eddy current brake control, Emergency stop-and-reverse motor control, Anti-sliding slope.

Indirect Field Orientation (IFO) Vector Control algorithm generates the maximum possible torque and efficiency across the entire speed range.

Advanced Space Vector Pulse Width Modulation (SVPWM) techniques produce low motor harmonics, low torque ripple and minimized heating losses, resulting in high efficiency.

Reverse polarity protection on battery connections.

Short circuit protection on all output drivers.

In low speed applications, DALA S1 BLDC motor controllers are more effective and reliable.
