hey guys, We are a team called Flipsky in China, making ESC for small electric vehicles based on VESC (BV open source project).
So far our work has gain thrust& praise from many builders around the world, here’s some review of our existing motor controllers from other electric skateboard builders on the esk8 forum , this might take a while to finish https://www.electric-skateboard.builders/t/new-vesc-from-china-seems-like-not-only-maytech-is-making-vescs-now/5207/361
Now by popular demand,we have the latest Dual 4.12 ready for sale~
and here it goes:
Dual ESC can reach 100A big current, give your board strong power
One PCBA board integrate two FSESC4.12 ’s function by internal CAN BUS circuit connection.
The mater and slave board connection can be switched On/Off
Delicate design in details for high quality assurance: add Anti-vibration silicon pad for screw heatsink and heat-transfer pad
Preserve Bluetooth module and RF module connections for both master and slave board
Super small size and light weight with heatsink: 79.6mm65mm18.8mm(LWH), wight: 147g
Firmware: latest version
Current:50A continuous/single, 100A continuous/dual , burst 150A/single, burst 300A/dual
Voltage: 8V-60V (Cells: 3-13S LiPo)
BEC type: Internal driver support
Timing: Software calibration
Cutoff Voltage: Programmable
Frequency: PWM input
◆ STM32F4 32Bit ARM micro-controller.
◆ DRV8302 MOSFET driver / buck converter / current shunt amplifier.
◆ 12pcs NTMFS5C628NL MOSFETs.
◆ Regenerative braking.
◆ DC motors are also supported.
◆ Sensored or sensorless operation.
◆ Adaptive PWM frequency to get as good ADC measurements as possible.
◆ Good startup torque in both sensored and sensorless mode.
◆ Duty‐cycle control, speed control or current control.
◆ Wireless WII nunchuk (Nyko Kama) control through the I2C port. This is convenient for electric skateboards.
◆ Optional PPM signal output. e.g. when controlling an RC car from a Rasp Berry Pi or an android device.
◆ The USB port uses the modem profile, so an Android device can be connected to the ESC without rooting. Because of the servo output, the odometry and the extra ADC inputs(that can be used for sensors), this is perfect for modifying an RC car to be controlled from Android (or Raspberry Pi).
◆ Sensored and sensorless (FOC) Field Oriented Control allows your electric skateboard to run with barely any motor noise, it auto-detects motor parameter since FW3.34.
◆ Many safety features such as current control and temperature control features.
◆ The motor is used as a tachometer, which is good for odometry on modified RC cars.
we are studying as much as we can to bring up the best solution . Any comment &suggestion are welcomed here.
