rpm

  1. Electric Motors
    At a given KV rating, will a motor with higher Watts have more torque? At a given watts rating, will a motor with lower KV's have more torque? Can we calculate KV from rpm and volts? Eg, 4900rpm/72V=68KV ?
  2. Controllers
    Hey guys, I have a curtis 1236 controller and a 10kW BLDC motor from golden motors. I am receiving no errors or anything on the controller or in software but my motor only spins at 309rpm when max throttle is received. The software is set up for a max rpm of 5000. any help would be appreciated...
  3. Controllers
    Hi, I want to operate Curtis DC Motor Controller's throttle via CAN-BUS (Curtis already support CAN input for throttling). In this regarding, I would like your confirmation that can we directly control DC Motor Controller's throttle from vehicle's OBD2 CAN-BUS pins (check attached image)...

    I am planning to convert a Maruthi Suzuki Esteem into pure electric car run by Switched Reluctance Motor drive . I contacted the motor suppliers and they asked for the details such as the torque of motor required , rpm , voltage , amps . Well from googling , i found a motor of 10 hp and 72 volt...
  5. All EV Conversions and Builds
    Its been awhile since my last post, but i have been doing alot of research. One question which is hard to find an exact answer is How do i limit the RPM of a Series wound dc motor? If this is done through the controller, what controller can i use, or can all of them do this? Can only certain...

    So I'm not sure if there is a thread for this already...I didn't find it. I was wondering what/if people use to measure motor RPM? Seems like it would be useful, especially given that many conversions done use the existing manual transmission, I would think it would be helpful for maintaining...

    Hello! for our rear wheel drive electric sports car project I am searching for a gearbox. We want to use the AC Propulsion motor and a suitable gearbox+differential combination for it. As noted from the AC Propulsion web site they have a max. 12000rpm and we want to reach about 130 mph. I have...

    Hello All, You may have seen my posts on other threads about a motor model I am developing. Well, I am pretty happy with it and so let me explain. First, the torque generated by a motor is given by the armature current times the "field" times some constant depending on the motor structure and...
