Re: CalMotors Motor/Controller Pricing

[Johannes H. <de...@jo...>]

  $1.5k really isn't much for the controller, especially 650V/1000A.
I don't use a SKAI module. Anyway, the SkiiP82 module (1200V, 95A) cost 
29€, the drivers are free samples.
All the other material and tools I have gone through since I started 
working on the inverter probably sums up to 1000€ ....

Peak power is rated at 313 kW and continuous at 258 kW.  Peak and continuous torque is 737 and 503 Nm respectively up to about 4,000 RPM with 7,000 RPM max speed and a 181 kG mass.   The motor is 3-phase liquid cooled PM.  Quantity one, the motor price was about $15K, the traction drive about $15K, and the control module around $1.5K.  This motor is a little larger than I think we need for the winch application.  Their GP750WC would suffice I believe.  I suspect their smaller yet motors in their line may be more appropriate for most of the EV applications at a reduced cost.

The inverter runs at 650V nominal and 1000Arms peak, 670Arms continuous - considerably above the Semikron power level.  They also have a smaller 450A inverter for their smaller motors.
