Brushless Motor Mean?
A brushless motor is a direct current (DC) electric motor that operates without the mechanical brushes and commutator of a traditional brush motor. It has distinct advantages over a brush motor and is more economical in the long run, although the initial costs are higher. Brushless motors are used in various aspects of trenchless construction.
A brushless motor may be referred to as a BLDC or BL motor. Synonyms include electronically commutated motors (ECMs, EC motors) or synchronous DC motors.
Trenchlesspedia Explains Brushless Motor
DC brush motors have been around since the late 1800s. One of the simplest types of motors, a brush motor includes a rotor, commutator, brushes, axle, and field magnet. But these brushes wear out over time. Brush motors are less efficient than newer brushless motors. And they can cause sparking.
Brushless motors were made possible with the advent of solid state electronics. The regulation of current, known as commutation, can be handled by software in a brushless motor. Advantages of brushless motors include a higher power to weight ratio, the potential for higher speeds, and electronic control.
The complex and varied field of trenchless construction has many uses for electric motors. They may be integrated into large tunnel boring machines or used to power narrow horizontal directional drilling devices. They are also part of power tools that may be present at any construction site. Because of initial costs, brushless motors are more prevalent at professional construction sites than in the hands of do-it-yourself repairmen.
