Product Information

An electric motor develops torque by keeping the magnetic fields of the rotor (the rotating part of the machine) and the stator (the fixed part of the machine) misaligned. the motor is a Kun-ray BLDC 72v 3000W motor, and i have an electrical controller box for it(YUYANG KING SERIES high power brushless controller, rated for 72v and 3000w the model number is the first comment if you want to copy paste it, i dont know what site i would use. The controller performs similar timed power distribution by using a solid-state circuit rather than the commutator system.

It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows. Others measure the back-EMF in the undriven coils to infer the rotor position, eliminating the need for separate Hall effect sensors.In the flat axial flux type, used where there are space or shape constraints, stator and rotor plates are mounted face to face. I do need to alter the low voltage protection circuit in the controller though, as it won`t run because it thinks the voltage from the 36v is too run down from the expected 48v. It consists of a rotating cylinder or disc divided into multiple metal contact segments on the rotor. I also already have a 36v 12ah lithium-ion battery pack and charger which I`d like to use with it for now (while I save more money up !

These benefits come at the cost of potentially less rugged, more complex, and more expensive control electronics. Some limitations of brushed motors can be overcome by brushless motors; they include higher efficiency and lower susceptibility to mechanical wear. Two key performance parameters of brushless DC motors are the motor constants K T {\displaystyle K_{T}} (torque constant) and K e {\displaystyle K_{e}} (back-EMF constant, also known as speed constant K V = 1 K e {\displaystyle K_{V}={1 \over K_{e}}} ).If it's hitting LVC on a 48V controller with a 52V battery, it's actually a little more dead than normal dead. This controller can drive both sine and rectangular motors and is made from high quality materials for superior strength and stability. Most electric bicycles use brushless motors that are sometimes built into the wheel hub itself, with the stator fixed solidly to the axle and the magnets attached to and rotating with the wheel. If your battery voltage sags 8 volts or more when you take off from the stop sign, your motor and controller are killing the battery.

I thought I would get more speed than I'm getting now, could a upgraded controller help with more speed ? Aeromodelling [ edit ] A microprocessor-controlled BLDC motor powering a micro radio-controlled airplane. The soft brush material wears down due to friction, creating dust, and eventually the brushes must be replaced. A typical brushless motor has permanent magnets that rotate around a fixed armature, eliminating problems associated with connecting current to the moving armature. Here's another photo with the hidden lines shown and my estimate of the circuit from the suggestions.The maximum power that can be applied to a brushless motor is limited almost exclusively by heat; [ citation needed] too much heat weakens the magnets and damages the windings' insulation. I figure it could be the high start up current of a motor, which could be 4~6 times of rated current. This instructable outlines what I did to make this project, but it is not a substitute for proper safety training in power electronics.
