Product Information

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. This control system is an alternative to the mechanical commutator (brushes) used in many conventional electric motors.

This instructable outlines what I did to make this project, but it is not a substitute for proper safety training in power electronics. This in turn means that the motor's internals can be entirely enclosed and protected from dirt or other foreign matter.My guess here is that my battery voltage is dropping below the controller's 50v lower limit, due to voltage sag and the controller is cutting the load. In the flat axial flux type, used where there are space or shape constraints, stator and rotor plates are mounted face to face. I also added the additional 2w 1k ohm to the group which did bring the combined res of those down to 250 ohm.

Most monitor charged and discharged voltages along with charging rate curves but others actually just have a counter that keeps track of the number of charge/discharge cycles. Brushless motors are commonly used as pump, fan and spindle drives in adjustable or variable speed applications as they are capable of developing high torque with good speed response. Some limitations of brushed motors can be overcome by brushless motors; they include higher efficiency and lower susceptibility to mechanical wear. On a different controller, you've got to try and identify the the voltage divider that deals with it, and change the resistor in the same way. Aside from the higher impedance of the wye configuration, from a controller standpoint, the two winding configurations can be treated exactly the same.The higher capacity controller may help with toasting your controllers, but may not get rid of the of the problem, if the battery is the root cause of the failures. I figure it could be the high start up current of a motor, which could be 4~6 times of rated current. Environments and requirements in which manufacturers use brushless-type DC motors include maintenance-free operation, high speeds, and operation where sparking is hazardous (i. For that pack to provide to the specs, it has to have some decent (3C) cells, so knowing that it came from a reputable source is important. A typical brushless motor has permanent magnets that rotate around a fixed armature, eliminating problems associated with connecting current to the moving armature.

And, nobody likes to bring this up, but your weight can be all the problem, if you are over 200 pounds. The pin on the microprocessor will either have an analogue input varying in the range between 0v and 5v or a digital input, where it'll be 5v above LVC and 0v below (or possibly vice versa). The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed, nearly instantaneous control of speed (rpm) and torque, high efficiency, and low maintenance. I am interested in 24 36V 800W DC Motor Controller By Lithium Battery 48V 1000W could you send me more details such as type, size, quantity, material, etc.The amount of power depends on the maximum current allowed by the controller, which is written on the label. Delta-connected windings can allow high-frequency parasitic electrical currents to circulate entirely within the motor. There is a trend in the heating, ventilation, and air conditioning (HVAC) and refrigeration industries to use brushless motors instead of various types of AC motors.

The amps at 36v have 3/4 of the power than they did at 48v, so a 36v 20A controller gives 3/4 of the torque that you get with a 48v 20A one.V LDO regulators (500 mA TLV755P; 400 mA TPS736) but the motor always has trouble starting (runs maybe 1 out of 10 tries). Brushless motor commutation can be implemented in software using a microcontroller, or may alternatively be implemented using analog or digital circuits.
