Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motor… ...

Best of all, the entire package will only run you about $20 in parts–including the position sensor! “Another BLDC motor controller?” you might think. “Surely, I’ve seen this before “.

In a DC motor, the stator is a permanent magnet and the rotor has the windings, which are excited with a current. The current in the rotor is reversed to create a rotating or moving electric field by ...

Moreover, changing from a stepper motor to BLDC requires a significant redesign of the mechanical subsystems, in addition to developing the control software.

This article describes ongoing internal project activities at eInfochips in the control systems domain for applications in motor and engine controls aimed for aerospace and automotive segments.

To help designers with these cost and software burdens, Fairchild Semiconductor developed the FCM8531 analog and digital integrated motor controller.

Toshiba Electronics Europe has launched a three-phase brushless DC (BLDC) motor control pre-driver IC for motors that require high rotation speeds. Suitable for server fans, pumps, blowers and suction ...

Using high-speed sensorless BLDC motor control in medical devices Introduction Brushless DC (BLDC) motors are widely used in medical devices due to their high reliability, high efficiency, low ...
