5KW 48V High-Efficiency AC induction Electric Motor for Tricycle Rickshaw
When choosing the model of the motor, you can consider motor power, cooling method, torque, rotation speed, max speed & mileage per full charge after conversion, battery voltage, space of the components and car original space, kit price etc to make a final most suitable solution.
You need to know clearly how fast you want the car to travel after modification. What’s the horsepower of the original engine? Do you retain the original gearbox? in this case, we connect the motor with the tractor orignal transmission by an adaptive plate
In an oil-to-electricity kit, the motor controller plays a crucial role:Motor speed and torque control. The motor controller regulates the speed and torque of the electric motor. It does this by adjusting the voltage and current supplied to the motor windings.
- Energy efficiency optimization.The motor controller helps to optimize the energy efficiency of the electric motor.
- Safety and protection functions
- System integration and communication
- The motor controller serves as a key interface between the electric motor and other components of the vehicle’s control system.
- Please be noted the system wire harness, gas pedal, gear stall switch switch are included in this controller link, we provide system wire diagram for each components so you will easily know system connection.
500W 48V to 12V High-Efficiency DC-DC Converter for Reliable Power Regulation
- The battery pack in an electric vehicle typically has a high – voltage output. For example, the battery voltage of many electric vehicles may range from 48V to 800V. However, different components in the vehicle, such as the low – voltage electrical systems (usually 12V or 24V), require a stable and lower voltage supply. The DC-DC converter steps down the high – voltage DC from the battery to a lower, regulated DC voltage (12V in this case). This allows it to supply power to components like lights, infotainment systems, and various sensors that operate on a lower voltage standard.
- If the original vehicle had a 12V electrical system for accessories and now has a high – voltage battery due to the electrification process, the DC – DC converter ensures that these 12V components can still work properly.

CMVTE Car Dashboard Display E-620 Instrument Cluster
- This is a 12V instrument cluster, which can indicate converted vehicle speed, battery capacity (SOC), turning signals, Forward&Reverse gear etc.
- The design and shape is not designed specially for Beetle/Bug, because original meter is small round type, but due to CAN BUS in the controller and battery BMS, the original car meter can only indicate speed of vehicle, can not indicate battery capacity. So you can choose to use a new electric instrument cluster like this type or to use a very simple battery capacity meter only, then you can keep the old Beetle meter to show speed, and this new simple battery capacity meter.
- Or you can choose a more premium smart meter which combines functions of media& entertainment and speed&battery indicator, except as a normal electric car meter, it also has bluetooth, music and movie player, reverse camera, car play etc. more details you can consult with our sales person.
48v 100ah lithium battery
Heavy duty unpowered rear axle for 3-4 tons commecial vehicles
Lithium batteries are the core power components of electric vehicles.
Compared with traditional fuel engines, lithium batteries can provide a quieter and smoother power output for the vehicle. This is because the operation characteristics of the motor are not like the vibration and noise in the combustion and mechanical transmission process of the internal combustion engine, making the driving experience of electric vehicles more comfortable during the driving process.
The PACK SIZE IS :860*190*170MM
We use EVE brand cells, the one of the best in China. Automobile grade BMS with CAN BUS in the pack.
If you have other special dimensions request, you can tell us and discuss how to make it.
Heavy-Duty Hauling Cart Rear Axle
The rear axle of a Heavy-Duty Hauling Cart is designed to be as 3-4ton loading capacity, and deliver high torque and reliable performance for transporting heavy loads at low speeds. The integrated drive axle combines the motor, gearbox, differential, and brake system into a compact assembly, simplifying vehicle installation and maintenance. Built with durable steel components and precision gears, it provides excellent traction, smooth power transmission, and long service life. Available in different gear ratios, axle lengths, and wheel mounting configurations, the axle can be customized to match specific load capacities and operating conditions. It is ideal for industrial carts, towing vehicles, and material handling equipment.
Successful Conversion Cases We've Delivered for Our Clients:
Here is the kit we installed for our customer‘’s heavy-duty hauling cart
Questions About Heavy-Duty Hauling Cart Motor Kit
Yes, we provide all electronic parts for conversion. We also provide wire diagram system, each part user manual, so you will have no obstacles for installation and connection of the system.
Yes, we provide motor spline coupler and adapter plate to install motor to original transmisison. But the original transmission’s clutch need to get removed. If you want to keep clutch, you need modify the spline coupler to clutch a bit. Because we do not have car in hand, so we bought a old transmission without clutch to make the coupler and adapter kit.
We provide two years for battery, and one year warranty for other parts. We only use top grade quality products. If any parts failure from manufacturing issues, we provide repair parts for replacement.
If we have stocks ready to go, the lead time is one weeek after order confirmed. if we have no stocks, lead time might be 4 weeks after order confirmed.
After you have discussed with sales manager all details of the order, he or she will make proforma invoice with all details and bank accounts for payment, normally payment is through bank to bank T/T. Other payment ways are also flexible to accept after discussion.
We only use top brand of cells in China, like EVE, like Gotion etc, most of the case we use EVE brand pure new and A grade cells to make pack. And in our battery pack we surely use real automobile grade BMS, not simple protection board.
We care about reputation more than our customers!
We are real manufacturer, not sales trade office/company, we started our motor production from 1995 in China. In conversion we now have more than 10 year experiencee. In the whole drive systems, we do not produce all parts, but motor we make, controller we provide CAN BUS and technical requests to our partner, same as lithium battery pack and wire hanress of the system, the design and CAN BUS are from us. other accessories like gas peda, meter etc we get from reliable partners.
Except motor and drive train solution, we also owns our own low speed electric vehicle assembly factory, its website/brand is www.gmtlsv.com
In short, we are EV expert with decades experience in China!
Yes, our key electronic components are with CE certificate for Europe markets, so at the moment, we ship to Europe like France, UK, Germany, Italy, Sweden, Belgium, Turkey etc.
