    9FET Infineion feels faster than 18FET???!

    How is this possible: 2 bikes, same motor (xlyte 4065), same battery (72V10Ah), one has a 9FET infineon, the other a 18FET. The 9FET is set to: Battery limit: 49.6A Phase limit: 125A Overcurrent delay: 0.5S The 18FET is set to: Battery limit: 74.8A Phase limit: 189.4A Overcurrent delay: 0.5S...

    Comparing Motor Case Temp to Internal Temp

    Is there any general temperature range to compare the outside case of the motor and what the internal should approximately be? Reason being is I am seeing higher temps reported on my CA than I was expecting. I am running a crystalyte 4065 on 72V LiFe and max 50A. Continuous watts at speed is...

    Infineon R12 regen voltage mod abnormality?

    I was just going to modify my R12 resistor from 1.2K to 1K to increase regen above 75V (https://sites.google.com/site/shelbyelectro/controllers-and-electronics/controllers/infenion-high-voltage-regen-r12-mod). When I opened my MCU I probed R12 with my fluke dmm and it measured .894K ohms? Is...

    Torque Arm for Giant Anthem rear hub motor?

    I am trying to source a good torque arm for a giant anthem MTB for a rear hub motor. The motor is a crystalyte HS4065R so it should be a bit beefy. I wanted to use the caliper mount, but the caliper mounting isn't IS compatible, but "post mount" style like on front forks. The rear brake section...

    Is my MAC 8T temp sensor lying to me?

    So I have a MAC 8T running at 48V on 26" wheels. I use it to get to/from work. This is my first ebike build and I did a lot of researching of components and never before did I read these motors overheat easily. ANYWAYS my route is approx. 15 minutes of nearly constant WOT @ 31MPH. With the...

    Power surging only when pedalling? [CAV3 + Lyen 12fet]

    I've noticed lately that when I am full throttle accelerating from a stop and pedalling at the same time that my power surges off/on briefly. Basically the motor cuts out completely for a brief moment less than a second. How can I determine if this is caused due to the motor controller or CAV3...

    CAV3 not outputting throttle signal to controller [help!]

    This is my first time using the cycle analyst. I have verified that that my throttle (magura) connected directly to the controller works fine. However, when I connect the throttle to my cav3 and cav3 to my motor controller nothing happens. I am using a Lyen controller which has the ca...
