STMicroelectronics's SPIMD20 is an
integrated motor drive with real time connectivity enabling brushless motor
manufacturers to create a proprietary motion control system based on a general
purpose brick. The shuttle version of the IMD is suitable for direct
integration to the permanent magnet synchronous motor (i.e. 6 Nm torque)
because of the reduced dimensions (165 x 60 x 26 mm). The Shuttle Drive is
designed to operate on a motor with a surface temperature up to 100 C . The IMD
performs all motor driving required functions including speed, position and
current loop execution, plus connectivity. Connection to the master is
performed via real time ethernet fieldbus, including but not limited to
EtherCAT as per IEC61158. The IMD is an open and flexible platform to execute
any other communication standard with the aboard FPGA (Altera Cyclone III type)
and the two microprocessors STM32F103 series. A basic software package is
available with SPIMD20. This software package includes PWM driving, current
loop and speed loop execution; all the above being synchronized to the
Advanced brushless motor control in a single module easy to
piggyback to the motor
Compact dimensions: 165 x 60 x2 6 mm, <0.5 kg weight
Up to 2 kW power with 800V dc supply, on 100C motor surface, can
withstand peak current of 40A in abnormal conditions
Integrated drive with real time connectivity via Ethernet-based
fieldbus (i.e. EtherCAT) and CANopen DS402
Canbus hand-shaking channel
RS232 interface for programming
2 Mb Flash memory aboard; also support removable Flash memory
Supports position feedback both with resolver or digital encoder
Motor current sensing with shunt sensors (2 phases)
Can perform vibration analysis and thermal sensing
Safe architecture to apply to most popular safety standards
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
