are you referring to its Peak Power perhaps? peak power is always higher than the true (RMS/sustainable) rating (RMS is based on ~0.7 of Peak voltage capability - we might be able to roughly assume 100V peak, vs 70v rms), but you wouldn't want to try running a motor at its peak limit really ... would be interesting to know what it's Peak power rating is though, and for how long it can handle it
(even 1-2 seconds would be very useful for this project, but i am doubtful it could take 2s of peak, depends on the thermal properties of the motor)
hopefully bosch can give us some useful data
Hmmm... sure that is true as electric motors just push all they have from the input and lowers the output as fast they possibly can. So a 0-50km/h run would push lots of power until 50km/h and after that push down on power to sustaining speed levels. 50km/h should need about 500w of power to sustain.
I don't think you need to worry about peak limit. Tell me what power (Volt x Amps) do you want the boost to be and how are you going to make it happen, another controller?
Peak and RMS are an extremely important part of any sine or PWM, or any electrical system which uses an alternating current; it is essential to know whether we are talking about RMS or peak, if we want to avoid destroying a motor or running it inefficiently.
I cannot answer the question of what power I would (could) make available to the motor, until i know the full technical specifications of the motor & its regen potential and control
Bosch has indicated that they only share technical specifications with OEM distributors
But I am hoping this is just a policy, and not a contractual obligation with the bike manufacturer, in which case I might be able to negotiate access to the data - if it is contractual, then this will have to wait until I have time to get the data experimentally (couple of months - unless someone else can do it in the meantime).
I should know soon either way, they are very responsive.
Hi guys,
Has anyone put a regen button on the bike to activate built in regen system?
Kind regards
