The scott drive is a 150kw peak for $3k, and there is a 100kw peak motor to $2.5k with it in a package....
I had see scottdrive once before. So I decided to check the it out once again here:
And here is something:
"This 100kW AC drive packages includes a purpose built EV inverter and a 3 phase permanent magnet motor. The motor is rated for 35kW continuous, with 100kW peaks for up to 10 sec"
So if the motor is capable of 100KW then what is the use of having a controller of 150KW ?
Besides the peak is for 10s which is not impressive. Also the Chinese made motor weighs 80kgs! Where as the Remy has a continuous rating of 60KW and a peak of 75KW. And the Remy based package weighs 59kgs in total:
This is typical of Remy since it has the patented HVH stator windings that lower the temperature upto 20 degC.
All this is ofcourse is no commercial for Remy! So , though the scott dive controller looks impressive with the packaged BLDC motor for USD 5495, the motor really fails to pass muster.
Also it brings me to another topic: why do people need so much power. To comfortably accelerate a 1000kg car, we only need a motor with 75KW peak. It is really cost that matters to bring EV's to the masses! Remy: Please do put good AC IM motors on to the off the shelf products..!
