Designing Ebike Controller: Cooling of Motor and MOSFET
http://ebikecontroller.blogspot.com/2015/08/cooling-of-motor-and-mosfet.html
Tuesday, August 11, 2015. Cooling of Motor and MOSFET. Due to the heavy current flow in Motor stator winding and MOSFET, there is a possibility of damage beyond certain temperature, so we have to cool it to maintain below optimal temperature. Which equipmets need cooling :. Due to high speed switching / regenerative braking / high current flow, the temperature increase suddenly, so we must need cooling. Cooling technique for Mosfet :. Air cooling - Simply placing a CPU fans in controller box keep the tem...

Designing Ebike Controller: Input Stage of BLDC Controller
http://ebikecontroller.blogspot.com/2015/08/input-stage-of-bldc-controller.html
Saturday, August 8, 2015. Input Stage of BLDC Controller. Input stage consist of rs232/USB and Microcontroller, we need to connect the rs232/USB to external interface to load the code into microcontroller. Coding the Microcontroller unit. In Progress, Will Update ! Subscribe to: Post Comments (Atom). EBike Performance and Tuning (Canada). Electric Bikes/Cars tech (Italy). Cooling of Motor and MOSFET. Input Stage of BLDC Controller. Output Stage of BLDC controller.

Designing Ebike Controller: Output Stage of BLDC controller
http://ebikecontroller.blogspot.com/2015/08/output-stage-of-bldc-controller.html
Saturday, August 8, 2015. Output Stage of BLDC controller. As output stage of the controller grab the source power (from Battery) and supply to the load (Motor), so i planned to design the Output portion first. Output stage componets :. Thick Busbar / Thick Soldering for connecting the Mosfet output to the Motor phase leads. Output stage Circuit :. MOSFET is the 3 terminal/lead electronic device, terminals are Source(S), Gate (G), Drain (D). P type Mosfet Symbol. Current flow occurs from battery to Motor.

Designing Ebike Controller: Welcome to Ebikecontroller
http://ebikecontroller.blogspot.com/2015/08/welcome-to-ebikecontroller.html
Thursday, August 6, 2015. I am very new to this ebike field, due to my own interest i started to thinking about ebikes and planned to create controller from scratch. My learning things about controller is Documented. In this blog fully, so please read all posts. it will surely help newbie to understand controller. How the interest came? Then i started searching in internet about hybrid and electric ebikes, this way i concentrated more on eBikes in my free time. Parts needed for Ebike :. I thought, we can...

Designing Ebike Controller: August 2015
http://ebikecontroller.blogspot.com/2015_08_01_archive.html
Wednesday, August 12, 2015. As we all know, Motor rating is fixed, and only thing that affect the eBike or car range is, BATTERY. Yeah, but battery technology improving these days due to intense researchs,. Conventional Batteries (we're using, also in production) :. Capacitor type batteries :. Upcoming (will be launched soon) :. Https:/ en.wikipedia.org/wiki/EEStor. Store 2700 F, and charge in few seconds, but only contraint is weight, 15w-50w/kg. DC Equivalent Series Resistance (ESR) 0.29 milliohm.

Designing Ebike Controller: Choosing the Motor and Battery for controller design
http://ebikecontroller.blogspot.com/2015/08/choosing-motor-and-battery-for.html
Thursday, August 6, 2015. Choosing the Motor and Battery for controller design. For designing the controller, we need the motor rating and battery voltage. Speed : 40-50 mph. Battery undervoltage Protection :. Method : PWM (Pulse Width Modulation). Assumption : 30-35 Wh per Mile. Motor : 48V 2000W. Torque : (still dont know how much i need, have to study). For calculating rpm (still have to analyse):. Https:/ endless-sphere.com/forums/viewtopic.php? 48V 2000W , Sensored. Tesla cars even use Li-ion cells.
