Description
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.
Integrated motor drive
Preliminary data
SPIMD20
The shuttle version of the IMD is suitable for direct
integration to the permanent magnet synchronous
motor (i.e. 6 Nm torque) thanks to the reduced
dimensions 165x60x26 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. However, 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 fieldbus.
