at lower system costs
The large appliance market is going through a period of significant

and touch screens.
• Meeting legislation requirements that span such areas as energy
efficiency, water consumption and safety, some of which have
regional variations that require a significant level of flexibility to be
built into the design. These requirements include:
Energy efficiency, with legislators pushing for appliances to use
less energy and reduce water consumption.
Safety requirements that ensure that new appliances will be safe
and reliable.

• Introducing better user interfaces, sharing more data with users
whether in faster spin speed in a washing machine, quieter operation
• Differentiating products, offering consumers a variety of features,
particularly in higher end premium brands.
Freescale considers all these market drivers in their new product
developments. As a result, the company has the system solutions that
help developers meet these challenges for almost any new appliance
imaginable—from the very basic to the most advanced and intelligent
electromechanical appliance.

consumption as well.
Since the refrigerator is always on, it can
consume up to 50 percent of a home’s energy
budget, with virtually all of that used to run
the compressor motor. Most refrigerators still
use a constant-speed on/off compressor.
However, variable speed compressors
are gaining traction in the market. They
enable more efficient cooling with precise
temperature control, thus reducing overall
energy use. In addition, manufacturers
are increasingly employing more efficient
brushless motors, which again reduces the
amount of energy consumed.
Delivering solutions for energy-efficient
motor control
Freescale offers a broad portfolio of MCUs
and DSCs that are targeted to deliver
energy-efficient advanced motor control
solutions. The portfolio starts with entry-level
8-bit MCUs for low-cost fans, compressors
and pumps. The next level includes a wide
family of high-performance 16-bit DSCs
with dedicated motor control peripherals
for advanced appliance applications. It then
moves up to 32-bit devices, which are often
preferred for higher end industrial drives.
Freescale is dedicated to providing
comprehensive system solutions that improve
the energy efficiency across the whole
spectrum of motor control applications.

Electric motors in commercial
heating, ventilation and air

MC13201 RF transceiver, creating the ideal
platform for many applications that need
simple but effective wireless communication.
ZigBee Supports Green Applications
Since day one, ZigBee technology has been
focused on green issues by reducing energy
consumption through automation. Among
other things, ZigBee technology is ideal for
sensing and control of energy consuming
devices such as lighting and heating/
ventilation/air-conditioning (HVAC) in both
home and commercial buildings.
ZigBee Home Area Networks provide
intelligent automation in the home, allowing
utility companies to reduce peak demand by
controlling devices such as washing machines,
while allowing consumers to schedule or turn
off devices based on energy rates.

Selected Home Appliance Reference Designs
DRM070—BLDC sensorless
based on DSC MC56F8013/23
The concept of the application is a
speed-closed loop brushless DC drive
without any position or speed sensor
needs. The application utilizes a sensorless
control based on back-EMF sensing
using dedicated low-voltage power
stage boards and controller board of
the MC56F8013/23 DSC.
DRM092—ACIM single-shunt vector control
with encoder based on MC56F8013/F8023
This application demonstrates a threephase AC induction motor vector drive
based on Freescale’s MC56F8013/F8023
DSC. Cost effectiveness and high reliability
were two key requirements considered.
Minimizing system cost, the algorithm
implements single-shunt current sensing
that reduces three current sensors to one.
The high range of motor operating speeds,
up to 18,000 RPM, is another advantage of
this reference design.
DRM102—PMSM vector control with
single-shunt current sensing using DSC
The application creates a vector control
PMSM drive with optional speed closed-loop,
using a quadrature encoder. It serves as an
example of a PMSM vector control system
design based on Freescale’s MC56F80xx
DSC. Vector control is an elegant method
to control a PMSM, where field-oriented
theory is used to control space vectors of
magnetic flux, current and voltage.
