More Stringent Energy Regulations Drive Motor Control Innovations
In today’s expanding industrial marketplace, the demand for electrical power is growing at an unprecedented rate. More than 40% of that electrical
demand comes from industrial electric motors of all sizes. Because of that phenomenon, governments and certification agencies worldwide are
introducing new regulatory legislation and more stringent energy efficiency requirements on electric motor OEMs and end users. Like many great
technological innovations, there needs to be a pressing demand in the market for change.
Analog Devices recognized years ago that this new era of smarter and highly efficient motor control systems would be the new standard for the motor
control industry. As part of that recognition, ADI embarked on an integrated and comprehensive motor control design program in collaboration with our
strategic partners, who are experts in their respective fields (MathWorks,® ARM,® Boston Engineering,® IAR Systems,® and Xilinx®), aimed at addressing
the entire system architecture to achieve the greatest level of efficiency while improving system accuracy and reliability.
By taking a system-level view (see Figure 1) of these new challenges, ADI was able to develop products that not only exceeded the individual
performance specifications but also represented the optimal interface between other functional blocks of the circuit. This system solution approach
enables ADI to offer industrial-based customers a completely integrated solution that fits their specific needs while helping them meet the new, more
stringent energy regulations.

Isolated gate drivers provide electrical isolation as well as strong gate drive capability, which
is often required for safety and robustness in many system architectures. The isolated gate
driver portfolio from Analog Devices offers designers performance and reliability advantages
over designs utilizing optocouplers or pulse transformers. Utilizing ADI’s proven iCoupler
technology, the isolated gate driver family offers the advantage of a maximum propagation
delay of 50 ns, less than 5 ns channel-to-channel matching, a 50-year lifetime for 400 V rms
working voltage, and galvanic isolation in a single package.

The new ADSP-SC58x processor family complements the SHARC+® cores and DSP accelerators with the addition of an ARM® Cortex-A5 processor to
deliver 24 giga-floating operations per second performance at under 2 W at high temperature. For highly complex, multiaxis motor control applications,
the task-sharing architecture allows the SHARC cores to focus on the highest precision algorithms for motor control, and the ARM core on time-sensitive
handling of the network stack. In addition, it contains safety features such as memory protection and divergent cores to meet the higher SIL ratings required
for the new systems.

Current Sense Amplifiers
Current sense amplifiers are used when a shunt resistor is placed in the high side or low side and high accuracy over temperature is required in
harsh environments. In motor control, normally the bidirectional capability will be needed. In order to build fast and accurate control loops, the step
response time and common-mode voltage step immunity are critical.

Difference Amplifiers
Difference amplifiers can be used for voltage and current sensing in motor control systems because
they can reject very high common-mode voltage. They will enable the low voltage converters to
interface with the high voltage industrial environment. This is especially true when functional
isolation is needed. Excellent drift and CMRR are the advantages of ADI’s difference amplifiers.

Precision Op Amps
Precision op amps are used as signal conditioning in the motor control systems. They will be used
as the sensor to ADC interface, thus the rail-to-rail input and output in high linearity will be needed.
They can also be used between the resolver-to-digital converter (RDC) and the resolver to provide
high current in high slew rate and accuracy. Wider bandwidth amplifiers will be used to detect the
fast changing current in the system.

AD-FMCMOTCON2-EBZ Evaluation Board
The AD-FMCMOTCON2-EBZ is a complete high performance servo
system on an FPGA mezzanine card (FMC) board. It provides a
complete motor drive system to demonstrate efficient and high
dynamic control of 3-phase PMSM and induction motors up to 48 V
and 20 A and enables users to model and implement motor control
algorithms rapidly for high performance servo systems by incorporating system modeling and design concepts using MathWorks modelbased design.
The kit consists of two boards: a controller board and a drive board. An
optional AD-DYNO2-EBS dynamometer can also be purchased through
Avnet and is intended to be an extension of the drive system.
The system reduces time needed to move a motor control system from
concept to production, by providing a prototyping system to verify the
hardware and control algorithms before moving to productions stage.

System Design Value for Any Motor Control System
Benefits
Model-based design was developed to help simplify the difficulties
and complexities inherent in control systems designs using traditional
nonautomated methods. Model-based design provides the designer with a
virtual design environment that enables developers to use a single model of
their entire system for data analysis, model visualization, testing, validation,
and eventually product deployment. Once the model is built and tested,
accurate real-time software is automatically generated, saving time and
reducing overall development costs as compared to traditional manual
coding. Model-based design with automatic code generation can also be
used in rapid prototyping, further reducing the design cycle. By its nature,
model-based design provides a structure for software reuse that permits
established designs to be effectively scaled up or down in complexity
depending upon the desired application and reliably upgraded in a more
simplistic and cost-effective manner.
