TDK Micronas to Begin Production Next Year
on New 3D Hall Effect Sensors
Magnetic Encoder Onboard Trinamic Motion
Control Module
TDK Corporation plans to begin production next year on an expansion
to its Micronas 3D HAL sensor portfolio with a new set that,
based on the Hall effect, enable robust stray-field compensated position
detection in automotive and industrial applications. They can
make magnetic field measurements in three dimensions and detect
stray-field position in two dimensions, enabling angular measurements
up to 360° with ferrite 2-pole magnets in addition to linear
measurements up to 35 mm by using two-pole bar magnets.
Both are dual-die SMD package versions of the company's HAL
3900 and HAL 3930 sensors and are designed to meet stringent
requirements for automotive safety. They suit a wide range of applications,
including steering-angle position detection, transmission
position detection, shifter position detection, accelerator and brakepedal
position detection.
The stray-field position detection can take both measurement types,
with additional 3D measurements resulting in two independent
angles for each die. HAR 3900 provides temperature-compensated
raw values of the magnetic field in X, Y, and Z direction via the SPI
interface while offering various low-power modes.
Patented 3D HAL pixel-cell technology which accurately measures
magnetic fields is the core of the family. Each sensor contains two
independent dies placed upon each other that are mechanically
separated and electrically insulated. The two dies measure almost
the same magnetic field, therefore ensuring synchronous output
signals for system redundancy.
TDK-Micronas is the center of competence for magnetic-field sensors
and CMOS integration within the TDK group. Since becoming
the first company to integrate a Hall-effect based sensor into CMOS
technology in 1993, it has shipped over five billion Hall sensors to
the automotive and industrial market. Headquartered in Freiburg,
Germany, it employs around 1,000 people. Production of the new
sensors is set to begin in the second quarter of 2022.

Trinamic has introduced a small, low-power servo control module
with integrated motion control for stepper motors that features an
on-board magnetic encoder. The single-axis controller-driver module
is designed for two-phase bipolar stepper motors used in robotics
and automation equipment. It optimizes speed and synchronization
of axes for quicker throughput while also reducing power loss
by 75 percent, says the company.
" When selecting an energy efficient drive, engineers tend to look at
servo drives. However, stepper motors have a considerably higher
torque than servo motors of comparable size at low speeds, " said
Jonas Proeger, director of business management. " This makes
stepper motors well-suited to get rid of a costly and inefficient gearbox
without losing positioning accuracy when you combine them
with closed-loop control: you get the efficiency of a servo motor at
the cost of a stepper motor. "
The TWCM-1321 module features a built-in magnetic encoder and
digital inputs for an optical encoder to simplify servo control for
advanced feedback and diagnostics. It is more than three times
smaller when compared with similar stepper motor solutions, says
Trinamic. The encoder can be used when a suitable magnet is
attached to the motor axis, enabling also closed-loop operation or,
alternatively, an optical encoder can be connected.
Based in Hamburg, Germany, Trinamic
Motion Control GmbH was acquired by
semiconductor firm Maxim Integrated
Products in 2020, bringing together
Maxim's analog power process and communications
technology with Trinamic's
motion control expertise. In August 2021,
Maxim was acquired by Analog Devices.
Trinamic specializes in ICs, modules, mechatronic
systems and motion control toolkits
for product developers and produces
a variety of motors and encoders. Among
them are its PANdrive smart motors that
are compact drives complete with all the
components needed for ready deployment
including motors ranging in size and power
along with encoders and control systems.
