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
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
