Dual BLDC Motor Control kit suitability

Other Parts Discussed in Thread: CONTROLSUITE

Hello,

I am looking for an integrated solution to control 2 brushless DC motors;

3 Amps each
3 phase
8 pole
There is a hall sensor in each
150VDC operating voltage (from battery)
2,000 rpm max
 
I am wondering if this kit would be suitable for this purpose to evaluate the solution:
 
TMDS2MTRPFCKIT: Dual Motor Control and PFC Developer's Kit
Tool/Software Folder: http://focus.ti.com/docs/toolsw/folders/print/tmds2mtrpfckit.html
 
A spec sheet on the motor we're using is attached also for reference:
 
Any feedback or input is welcomed and appreciated!
 
Thanks again!
Paul

    Paul,

    The TMDS2MTRPFCKIT is a low voltage (safe) kit used to prove the concept of spinning 2 motors under one device.  As such the max DC voltage that the TMDS2MTRPFCKIT can have inputted is only 24-48Vdc and it can only deliver about 50W per motor.  Because of this it will be a scaled down version of your system.  The software written for this kit also drives a sinusoidal output (which is good enough to spin BLDC motors), but is perhaps better suited to permanent magnet synchronous machines.

    I might recommend the TMDSHVMTRPFCKIT instead.  With this kit, you will be able to prove out spinning your BLDC motor with a C2000 device and get your control loop working correctly.  There are multiple software projects that are designed to work with this kit and they are designed to show BLDC, PMSM and ACI control with various sensor/sensorless options.  These projects are documented well.

    After getting one motor to spin and work correctly, the task would then be to duplicate what exists with a second motor, which is certainly possible with the bandwidth and resources of a C2000 device.  This will be a tedious precision-oriented task, but is do-able.

    Note that all software for both kits can be downloaded for free through controlSUITE.


    Thank you,
