Hi and
to the forum.
The rpm/V will vary with the voltage rating of the motors, but according to the dynamometer data on the
goldenmotor.com website, here are the approximate rpm/V figures for the following motors:
3kW 48V = ~94
3kW 72V = ~60
5kW 48V = ~91
5kW 72V = ~59
5kW 96V = ~45
The voltage rating of the motors will affect both the Phase winding resistance and inductance.
Unfortunately, I have not seen any figures for the 3kW motors, but the figures for the 5kW motors are as follows:
- Phase Resistance (Milliohms): 6.2/48V; 12.0/72V; 36.0/120V
- Phase Induction(100KHZ): 68uH/48V; 154uH/72V; 504uH/120V
The 3kW and 5kW motor variants all have 8 magnets, which equals
4 pole pairs.
I can't find any details on the no-load current at
low speeds for any of these motors, so I don't know how you'll be able to derive the Hysteresis torque and Eddie current torque for any of these motors.
Regarding the controller parameters, I have not seen any resistance figures published for any of the EZKontrol controllers.
Battery Current Limit
(Max Bus Current) and Phase Current Limit
(Max Phase Current) will obviously vary dependent upon the exact model of the controller, but these figures are available on the goldenmotor.com website in the
motor controller section.
Unfortunately, some things are never as simple and straightforward as you would like them to be.
