What’s the difference between 36V 500W,36V 750W and 48V 1000W hub motors | Leafmotor

Q:What's the difference between 36V 500W,36V 750W and 48V 1000W hub motors A:36V 500W,36V 750W and 48V 1000W hub motors are all used for electric bikes,also called electric bike motors.They have the same figuration.These three motors are all made of the same hub,covers, axis,bearings,hall sensor.So they look the same,but they have different magnet and rotor-winding. 36V 750W and 48V 1000W are the same hub motors,just work at different voltage,has different watts. But for 36V 500W × 36V 750W（48V 1000W） The difference between them is that gauge of the coil wires,turns number of the coils and height of magnet. The height of 36V 500W hub motor's magenet is 24mm,but 750W hub motor reach 30mm.Picture enclosed. In market,36V 500W is easy to find it,but difficult to find real 36V 750W hub motors. In China,36V 500W(48V 600W) motors are very popular and used for electric bikes,these motors seem to ours,but No.The height of our magnet is 6mm more than as usual,reach 750w or 1000w.North America like them,more like high speed motors,we can customize motor speed as customers' actual need. Now 26" 36V 750W bike wheel reaches 20m/h and the speed of 48V 1000W is 27m/h.It's standard speed.

Now to complete the delivery period, the Sanyo Haier and business as usual operations, customer service will be a seamless transition.

Bldc stepper motor for electric bike | Leafmotor

In the subsection of section Classification of electric bikes we looked at options for motors used in electric bicycles, their positive and negative sides. Let's try to analyze and compare the characteristics of electric motors (bldc hub motor and bldc stepper motor)from one well-known manufacturers: Leaf Motor (China). Leaf Motor produces sets with a motor-wheels, and the other kits that use a chain drive. The analysis will be based on data from well-known owners of electric bikes site EValbum, the characteristics of the manufacturer, and other sources on the Internet. Therefore all figures are approximate, and the findings are an expression of opinion ePowerBikes.ru As stated by bldc hub motor, voltage motor-wheel independent maximum speed:24V - 25 km / h, 36V - 32 km / h, 48 V - 50 km / h. These data are confirmed by practical measurements elektrovelosipedistov. The maximum velocity at the start line set bldc stepper with 42 km / h and end with 120 km / h. Those cyclists who speed up to 30 miles is enough, can choose a motor-wheel 24V,36V,or 48V. For practical information, electric bikes with a motor-wheel 36V 500W and lithium-phosphate battery 10Ach a maximum speed of 32 km / h and can cover a distance of 50 km. For those who want to 'fly' at speeds above 50 km / h, suitable set of Leafmotor 601kit-1 48V 1000W e bike kit. Compare sets with the same maximum speed - 45 km / h - a new set 601kit-1 48V 1000W bldc hub motor and bldc stepper 48V 500W. Based on the characteristics of graphs,we choose the rate at which engines operate most efficiently, it is 40 km / h for both. For the same power consumption in this mode - 420-440 watts, at the time of bldc stepper motor is a little more, but this is neglected. It turns out that energy costs are the same at a speed of 40 km / h. We obtain a theoretical figure 10.5 Wh / km, although in practice the number is likely to be greater. Now suppose that we face a steep hill. The maximum torque developed HBL hub motor – 30 Nm, bldc stepper motor - 38 Nm. For the calculation we use a calculator elektrovelosipedista. Let Curb weight of a bicycle with the stepper motor - 100 kg, the rise of 7% of 3.5 km. To overcome this recovery time is needed more than 26 Nm on the wheel 26. " Power expended by the motor-wheels 601kit-1 e bike kit is more than 1060 W at a speed of 35 km / h. Total energy costs - 106 Wh. What makes it with bldc stepper-kit? He switched to the lowest gear, increasing time and decreasing the rate of 2.4 times (for cassettes with a maximum star 34t). At 2600 revs / min, torque on the shaft of the gearbox - 11 lb lost by power - 390 watts, speed - 14.5 km / h. Cost of energy to overcome lift - 94 Wh. Switching gears allow the rider to use the bldc stepper with the maximum efficiency of ~ 83% versus 73% for motor-wheels 601kit-1. As you know, the availability of transmission system for a bicycle greatly expands the range of effective use of a set of bldc stepper motor. These are one of the best available right now,s o if your´re looking for one, check it out. 9-14 cassette on the wheel 26 "will change the torque of 6 to 60 Nm and a speed in the range of 11.5-45 km / h (about 2100-2900 revs / min) at an efficiency of above 80% (included efficiency gearbox and chain drive). Efficiency of the motor-wheels 601kit-1 has a maximum value of 78% of torque 10-16 Nm. It is logical that upon arrival at the ideal surface Bonneville Salt Lake in Utah, at 40 km / h, both test sets will spend the same amount of energy. But as soon as the trial will move to an area with hilly terrain, a set of bldc stepper will be more economical than 601kit-1, and of course will be able to overcome the ups who his opponent will not under force. We note again that the higher efficiency is achieved when using leafmotor’s bldc stepper motor in the range of maximum efficiency, extended thanks to gear bike.

replace hall sensor for 750w hub motor | Leafmotor

The hall sensor is a transducer that varies its output voltage in response to a magnetic field. Hall sensors are used for proximity switching, positioning, speed detection, and current sensing applications. Three phase bike motor has three hall sensors inside that are used for electric bike widely. 36V 250W brushless geared motor is popular in Europe, but in North America, people like 36V 750W hub motor more. More and more people order and enjoy these two types of DC hub motors that are called classic electric bike motors. Now they have received by most of customers because of good quality. But when ride this hub motor bike and climb hill for a long time. Sometimes over current or over head will break motor controller's MOSFET or hall sensor. Hall sensor is broken. The hub motor can't work. Unless your controller can drive sensor-less motor. Buy a new motor, cost more. Replace hall sensor, cost less. Below we first instruct one type of 750w electric bike motor . If hall sensor is broken, power on battery, you will find battery gauge works, horn works, lights work, everything is good, except when you turn your throttle, the hub motor wheel can't run. Step 1: Retest this hub motor and make sure it does be broken. Do you have voltmeter? Still connect all wires and power on. First measure 6-pin hall sensor plug, the voltage as below: 1.The voltage of red and black is about 4.5V; 2.The voltage of yellow and black is about 4.5V or 0V;(use hand to turn hub motor, the voltage will change from 0V-4.5V) 3.The voltage of green and black is about 4.5V or 0V;(use hand to turn hub motor, the voltage will change from 0V-4.5V) 4.The voltage of blue and black is about 0V or 4.5(use hand to turn hub motor, the voltage will change from 4.5V-0V) If you can get above data it's no problem with bike conversion kit system. If the voltage of Item 2 (yellow and black wires)can't change from 0V-4.5V,Please replace this hall has a yellow wire connect. You should prepare some tools and material: 1.Hexagon wrench (Necessary) 2.Hammer (Necessary) 3.Screwdriver 4.electric iron 5.A-B glue 6.insulated paper, insulated wire 7.scissors 8.New hall sensor Step 2: Take off nuts and gasket on axis and use hexagon wrench to loose 16 screws. Step 3: Make the electric bike motor stand and cable is bent inside. Left hand hold the hub motor and use hammer to knock the axis. Step 4: After some knock, the cover will take off hub. Step 5: Use the same way to knock the other axis, the other cover will also take off hub. Step 6: When both side covers are off hub, next we should take out the rotor-winding. Make the axis stands on the ground, both hands press hub motor, the rotor-winding will out of hub. Step 7: There are three hall sensor in three grooves around the rotor. Use scissors to remove insulated wire and insulated paper. You will find 9-pin(three hall sensor)connect to PCB on rotor-winding. Each hall has three pin: 1:+ , 2:- ; 3:signal For example: Hall A: 1:+ , 2:- ; 3:Yellow wire Hall B: 1:+ , 2:- ; 3:Blue wire Hall C: 1:+ , 2:- ; 3:Green wire Step 8: Just now had known yellow wire hall sensor was broken. Please use electric iron to remove Hall A and use A-B glue to fix new hall sensor. Use insulated paper, insulated wire to fix PCB. Then re-build this hub motor. Step 9: Test as step 1.If can get the data from each hall sensor. Congratulate. Power on battery, the hub motor wheel works.
