Other Parts Discussed in Thread: MCF8329A
I have an MCF8329EVM connected to a BLDC motor with no load. The motor is 36V, 1760W rated . We have filled in the basic information in the Motor Studio GUI but every time I run the Smart Tune function, it results in the message "Configuration Failed". Nothing we do changes this outcome. The motor is a Vipxyctw3dski7655665 (Amazon.com: Vipxyc Scooter Electric Motor, 560KV Alu Shell Outrunner Brushless Sensored Motor for E-Scooter Skateboard Bike Kit, Brushless Motor : Sports & Outdoors )
These are the settings I have put in:
- “No Load” selected – we don’t have any load connected to the motor
- Rated Voltage set to 36V – this is correct for this motor (in our product we will use a 48V motor, but we don’t have one of those yet)
- Rated Current = 48,88A from the rated Watts
- Rated Speed = 1050Hz calculated from the motor datasheet using max speed = 9000rpm) & the number of pole pairs = 7 . 7 pole pairs = 14 poles.
Using your formula Speed in Hz = N x P/120 = 9000 x 14/120 = 1050Hz - Control Mode is set to “Speed Mode”
- MCF8329x Shunt Resistance = 1mW from MCF8329A documentation
The motor spins when I try to generate the configuration, but it results in the message "Configuration Failed". What can I do to get it to work?
