Abstract:This paper discusses an inverter-driven single-phase brushless dir=
ect-current (BLDC) motor assembled by a housing for a cordless vacuum clean=
er. Air gap in the single-phase BLDC motor is asymmetrically designed to sa=
tisfy starting and continuous torque by considering voltage fluctuation in =
a battery. By varying both advance and conduction angles in response to the=
 change of battery voltage, the proposed single-phase BLDC motor with asymm=
etric air gap is able to maintain sufficient output power. The system effic=
iency of a vacuum cleaner driven by the proposed motor assembly is estimate=
d by means of fluid dynamics in air watt, and it is also verified experimen=
tally. From the results of the condition of 100,020 r/min, it was confirmed=
 that the motor efficiency was in good agreement with the estimated efficie=
ncy, and air flow efficiency of 45.7% and system efficiency of 41.8% were a=
chieved.Keywords: single-phase BLDC motor; cordless vacuum cleaner; computa=
tional fluid dynamics; flow path efficiency

Our advanced design and optimization modeling software, PrintStator, signif=
icantly reduces design cycle time, eliminates human error, and quickly tran=
sforms your requirements into an optimized motor design with exact operatin=
g characteristics.

Motor and application tuning is performed through the Motor-Expert 2.0 GUI =
with control loop coefficients being updated in real-time without having to=
 recompile code. The interface also enables users to visualize system opera=
tion, displaying the status of data, including current, speed, status, curr=
ent error, and speed error. A diagnostics field within the software interfa=
ce provides insight into inverter and motor operation.

The complete BridgeSwitch, Motor-Expert 2.0 and three-phase motor control s=
oftware solution is available today and includes a downloadable manual for =
the software architecture, APIs, functions, calls and variables used in the=
 code.

The new three-phase motor control code and Motor-Expert 2.0 tool are offere=
d as part of the Motor-Expert Suite under a free license for use with Bridg=
eSwitch ICs. BridgeSwitch ICs are priced starting at $1.69 in 10,000-unit q=
uantities of the chipset. For further information, contact a Power Integrat=

Hi, thank you for the insightful information in this article, it has helped=
 a lot. I would like to design a slow outrunner BLDC motor with nominal spe=
ed at around 160 RPMs. I plan to control it with a typical ESC. How do you =
suggest to design the stator (how many windings and how to wind it), and th=
e rotor (how many poles)?

Motor-CAD is used in various and complex systems such as hybrid/electric ve=
hicles, aircraft motors, wind power generation, submersible pumps, hermetic=
 compressors, conveyer rollers and motorsport. We have an excellent track r=
ecord of providing value for money services, applying engineering expertise=
 and software tools to design products across a spectrum of applications.

Fortunately, this sector is rapidly maturing and silicon vendors now offer =
a wide range of highly-integrated BLDC motor driver power MOSFET chips with=
 either external or embedded microcontrollers to simplify the design proces=
s, while also lowering component costs. This article will explain how the d=
esigner can take advantage of these latest chips to ease the design process



By far the most common configuration for sequentially applying current to a=
 three-phase BLDC motor is to use three pairs of power MOSFETs arranged in =
a bridge structure, as shown in Figure 2. Each pair governs the switching o=
f one phase of the motor. In a typical arrangement, the high-side MOSFETs a=
re controlled using pulse-width modulation (PWM) which converts the input D=
C voltage into a modulated driving voltage. The use of PWM allows the start=
-up current to be limited and offers precise control over speed and torque.=
 The PWM frequency is a trade-off between the switching losses that occur a=
t high frequencies and the ripple currents that occur at low frequencies, a=
nd which in extreme cases, can damage the motor. Typically, designers use a=
 PWM frequency of at least an order of magnitude higher than the maximum mo=
tor rotation speed.

Although PSpice is designed as an electronic circuit simulator, you can als=
o use it to simulate mechanical or electromechanical systems. Analog Behavi=
oral Modeling makes simulating mechanical systems much simpler. An example =
of an electromechanical system which can benefit from PSpice simulation is =
a Brushless DC motor.

Engineers working in electromagnetics and electric motor design need to be =
able to accurately predict how their devices will perform in real-world ope=
rating scenarios. The COMSOL Multiphysics simulation software and the AC/DC=
 Module can be used to model electric motor designs.

Another innovation in the field of compact drive technology for the EJ seri=
es is the EJ7411 BLDC motor module. It offers high control performance in a=
 very compact design for the medium power range of BLDC motors. Available m=
odule inputs include 2 x end positions, 1 x encoder, and 3 x Hall sensors, =
while outputs include 1 x BLDC motor, 1 x motor brake, 1 x sensor power sup=
ply and 1 x encoder power supply. The fast control technology and support f=
or connection of an incremental encoder make it possible to achieve both ve=
ry high speed profiles and dynamic positioning tasks. Numerous monitoring f=
unctions, such as overvoltage and undervoltage, overcurrent, module tempera=
ture and motor load (via calculation of an I2T model), result in maximum op=
erational reliability. Further features of the 24 mm wide EtherCAT plug-in =
module include 4.5 A output current (Irms) and support of the distributed c=
locks functionality.
