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
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
