Compared to traditional brushless motors, brushless motors have the following advantages

1.High efficiency: Due to the use of electronic commutation in brushless motors,

which reduces energy loss caused by mechanical commutation, the efficiency of brushless motors is higher than that of brushless motors.

2.High speed: Due to the lack of mechanical commutation in brushless motors, higher speeds can be achieved.

3.High reliability: Due to the lack of brushes, brushless motors have a longer lifespan and lower maintenance costs.

4.Low noise: Due to the lack of mechanical commutation and brush friction noise in the brushless motor, the noise is lower.

5.Low electromagnetic interference: Due to the lack of brushes in brushless motors, electromagnetic interference is lower.
 

Overall, brushless motors have the advantages of high efficiency, high speed, high reliability, low noise, and low electromagnetic interference, making them widely used in many application fields, such as electric tools, electric vehicles, drones, robots, etc.

Brushless motor is a typical electromechanical integrated product, composed of the motor body and driver, widely used in high-end recording consoles, video recorders, electronic instruments, and automated office equipment.

Zeroth Order Rating

In determining the rating of a machine, we may consider two separate sets of parameters. The first set, the elementary rating parameters, consist of the machine inductances, internal flux linkage and stator resistance. From these and a few assumptions about base and maximum speed it is possible to get a first estimate of the rating and performance of the motor. More detailed performance estimates, including efficiency in sustained operation, require estimation of other parameters. We will pay more attention to that first set of parameters, but will attempt to show how at least some of the more complete operating parameters can be estimated.

Voltage and Current

Round Rotor To get started, consider the equivalent circuit.

This is actually the equivalent circuit which describes all round rotor synchronous machines.

It is directly equivalent only to some of the machines we are dealing with here, but it will serve to illustrate one or two important points.

What is shown here is the equivalent circuit of a single phase of the machine. Most motors are three-phase, but it is not difficult to carry out most of the analysis for an arbitrary number of phases. The circuit shows an internal voltage Ea and a reactance X which together with the terminal current I determine the terminal voltage V. In this picture armature resistance is ignored. If the machine is running in the sinusoidal steady state, the major quantities are of the form:

Ea = wAa

cos (wt +6) & = Vcoswt

Ia= Icos (wt -+)
