hello all,
I want to share my recent experience about Lyen controller:
I bought 3 controllers:
1st one: sensorless 6 FET programmable. with shipping cost >100euros
2nd one: sensored 6 FET programmable > 100 euros.
3 rd one: sensored 12 FET M2 EB318, programmable about 200 euros.
the 6 FET SENSORED controller burns after 3 minutes: too much current: phase current must be lower than 60A otherwise it burns MOSFET even if it can support 100A. I replace all MOSFET and after 10 minutes again, it burns at new.
after discussing with Edward Lyen, he recommends me the use of a 12 FET Mosfet. with shipping cost + options, it costs me 200 euros.
the controller works fine but the motor can't go into high RPM. climbing hill is impossible! however current reaches 30A under 60V!!!! but speed is limited to 25-30 km/h.
I finally decide to use the stock controller i bought with my hub motor and it works very fine (shipped with my BPM V2): high torque, high speed: climbing 20%, top speed about 40 km/h.
conclusion: I DON'T RECOMMEND LYEN controller for GEARED HUB MOTOR like BPM or MAC motor: no torque, no speed even if current is set at 30A or above. you will lose your money. prefer buying High speed controller for GEARED hub motor as it is a reducted motor, for 1 RPM of the wheel, the motor will do 3 RPM.
Nevertheless, for GEARLESS hub motor (like Magic pie) it works fine as the RPM of motor is lower than GEARED.
with programmable cable it works fine with custom setup.
And if you want to save money, avoid the mini monster 6 FET controller: even if the MOSFET are IRFB4110, if current reaches 30A MOSFET will burns late or soon.
