3. Motor types
and their
fundamentals

4. Electric motor: classification
4
• PMSM: 3-phase Permanent magnet
synchronous motor
• BLDC: Brushless DC motor
• ACIM: 3-phase Induction motor and
Single-phase induction motor
• These are the most commom
motors in the market.

5. DC Brushed motor
5
• Brushed DC motor are commonly used in
industrial applications such as robots, valves
and healthcare equipment. Current automotive
solutions have plenty of DC motors. Toys are
the universe of small DC brushed motors.
• The brush DC motor is driven by directly
applying a voltage to the motor leads.
• Efficiency is good, about 70 to 85% due to its
permanent magnet stator.

6. DC Brushed
6
• The rotor is composed of a group of coils
• The stator magnetic field is generated by a permanent
magnet
• DC Motor current and torque are proportional
• DC Motor voltage and speed are proportional

7. DC Brushed
7
• When only one direction of
rotation is required, a single switch
topology with PWM modulation
can be used to vary the voltage
applied to the motor, and thus to
control its speed.
• When positioning is required or
when both directions of rotation
are needed (e.g. car windows) a
full H-bridge with PWM control is
used.
• ST offers a full set of integrated
motor drivers and power
MOSFETs and gate driver ICs to
implement the required H-bridge.

8. Universal motor
8
• Universal motors can be used with AC or DC
supplies and are commonly used in consumer
appliances such as mixers, fans and vacuum
cleaners.
• Both stator and rotor are made by coils
• Most universal motors are unidirectional.
• Bidirectional motors using two coils on the stator
can be driven by applying a voltage to only one of
them for the respective direction. Alternatively,
permuting the Stator connection related to the
rotor.
• Efficiency ranges from 30% for small motors to
75% for large motors.

9. Universal motor
9
• The advantages of universal motors are high starting torque, very compact design
and high speed.

10. • A simple controller with an AC
supply can be implemented using
a low-end microcontroller and a
single Triac or an AC switch.
Universal motor
10
• Universal motor driver using DC mode
topology can use chopping control
thus improving efficiency and acoustic
noises due to 3rd harmonic reduction.

11. Stepper motor
11
• Stepper motors are widely used in holding and
positioning applications in the computer, security,
industrial automation sectors.
• The stepper motors are designed to keep a
target angular position.This objective is
obtained by splitting the rotation of the shaft in
small fractions named steps.
• There are different types of stepper motors:
Unipolary, Bipolar (most common), 3-phase, 5-
phase.

12. Stepper motor
12
• In bipolar stepper motors, current can flow in both
directions;

13. Stepper motor
13
• Dual full-bridge converter is required to drive the two
windings of a bipolar step motor. ST fully integrates
monolithic motor driver ICs, embedding digital controllers,
power devices and protection functions.

14. Stepper motor
14
• Full-step 1 (1,2,3,4) and full-step 2 (1b,2b,3b,4b):
according to adopted stator magnetic field sequences;
• Half-step: jointing Full-step 1 and 2.
• Microstepping: Starting from half-
step concept, it is possible to further
increase the number of stable
mechanical positions using the
microstepping technique.

15. • Permanent Magnet synchronous motor
and Brushless DC motors are replacing
DC brush motors more and more in many
applications due to advantages such as
higher efficiency, quieter operation and
better reliability.
• PMSM and BLDC, both are three-phase,
brushless and synchronous motors (rotor
electrical speed equals to stator excitation
frequency).
BLDC - PMSM motors
15
• The rotor magnetic field is
always present, and it is
generated by a permanent
magnet glued on the surface.
• The highest torque among
motors, efficiency 85% - 95%

16. BLDC - PMSM motors
16
• The scanning of the 6 driving combinations of the six
steps is synchronized by the rotor position.
• The rotor position can be monitored using Hall sensors
or a BEMF sensing technique (sensorless).
• 6-step driving imposes a current between two of the
three phases leaving the third one floating. In this way
the stator magnetic field can be positioned in 6
discrete directions.
• BLDC: 6-step driving
• Rotation induces trapezoidal Back Electro-Motive Force
(BEMF) in motor phases; it gives best performance
(torque steadiness) when driven by 6-step method.

17. BLDC - PMSM motors
17
• PMSM: Sinusoidal driving
• Rotation induces sinusoidal Back Electro-Motive Force
(BEMF) in motor phases; it gives best performance (torque
steadiness) when driven by sinusoidal phase current
• By applying three sinusoidal voltages with a delay of
120°in the motor phases it is possible to obtain three
sinusoidal currents generating a rotating magnetic field.
• allows a smoother operation compared to the 6-step
method.
• The Field Oriented Control (FOC) algorithm allows to
obtain the maximum performance from a PMSM motor.
• Optionally, the Space Vector Modulation can also be
used. The SVM imposes a sinusoidal voltage between
to adjacent phases applying a non sinusoidal voltage
to the motor leads

18. BLDC - PMSM motors
18
Despite their different
structures, all three-phase
permanent magnet motors
(BLDC, PMSM) are driven
by a pulse-width-modulated
(PWM) three-phase bridge
(three half bridges). Special
algorithms are applied to
supply the motor with
variable frequency and
amplitude of voltages.

19. • AC induction motors, or Three-phase induction
motors are brushless motors.
• An AC induction motor is one of the simplest and
most reliable types of electric AC motor, with the
power ranging from a few watts to many
kilowatts.
• This motor is called Asynchronous motors (rotor
electrical speed slips from stator excitation
frequency).
• The industry looks forward to find different ways
to design and control such motors, power and
speed.
• The motor efficiency is quite good, from 75% to
85%
ACIM or AC3P motor
19

20. • The stator is copper-coils and the rotor is typically an aluminum or copper squirrel
cage.
• By applying three sinusoidal voltages with a delay of 120° in the motor phases for
3-phase motor it is possible to obtain three sinusoidal currents generating a
rotating magnetic field.
ACIM or AC3P motor
20

21. 21
• It is very simple to implement highly efficient Variable-Frequency Drive (VFD)
motor control, for low-power range motors. Scalar control.
• For mid - high power range motors, the Field Oriented Control (FOC) algorithm
allows to obtain the maximum performance from ACIM motor.
• Optionally, the space vector modulation (SVM) can also be used. The SVM
imposes a sinusoidal voltage between to adjacent phases applying a non
sinusoidal voltage to the motor leads.
100%
50%
0%
ACIM or AC3P motor

22. • The typical drive configuration
is a three-phase bridge (3 half-
bridges) modulated (PWM) to
provide three sine wave
voltages to the stator
• The driving portion can be
composed of power MOSFETs
or IGBTs with high-voltage
gate drivers, or power modules
integrating three half-bridges
and related gate driving stage.
• FOC or Scalar control
algorithms are implemented in
the microcontroller that
controls the inverter.
ACIM or AC3P motor
22

23. • A single-phase AC induction motor is in fact a
dual-stator coil, single-phase supplied by AC
mains.
• Different types of single-phase motors, with or
without shift-phase capacitor, largely used by
compressors, small pumps, garage door
system, etc.
• Induction motor is a brushless motor. Reliable
(unless by the PSC), and simple.
• The motor efficiency is OK, 60% to 70%
Single phase ACIM motor
23

24. Single phase ACIM motor
24
• Speed control can be don by a triac
arrangement, if unidirectional control, or
dual triac if bidirectional control.
• Phase-angle control provides low
efficiency, however it is simple and chip.
• Speed control can be done by a Inverter
system; uses 3 half bridges, 90º /180º
phased each other, eliminates the
capacitor.
• Speed control can also be done by AC
chopper, but also not a very simple
solution.
