🔥About the MY1020-WG（with heat sink）
✔Two Power Versions for Different Build Needs

48V 2000W – balanced power, suitable for daily riding and moderate upgrades
72V 3000W – high-output performance for speed-focused or heavy-load projects
The heat sink keeps both versions running cooler, enabling more stable performance under continuous load.

✔Excellent Compatibility Across Multiple Vehicles

Razor MX650 / MX500 / SX500 / RSF650
Electric Go-Karts & Drift Trikes
Mini Motorcycles, Mopeds, E-Scooters, E-Bikes
DIY electric vehicle builds & engineering projects
Compatible with Kelly, FarDriver, and Kunray NS12 controllers, ensuring simple and direct installation.

✔Enhanced Cooling System for Higher Performance

This upgraded version adds a dedicated aluminum cooling cover, significantly improving heat dissipation during long-duration riding or high-load conditions
The heat sink increases airflow around the motor body, helping the MY1020-WG maintain stable temperatures even during aggressive acceleration or uphill riding.

✔Smarter Thermal Protection with Dual Safeguards

Not only does the motor include the original KTY83-120 temperature sensor, but the external cooling cover further reduces heat buildup.
With the programmable controller, riders can set thermal limits to protect the motor from overheating — now with double-layer protection (internal temperature sensor + external heat sink).

✔Heavy-Duty Power Delivery with 6mm² Phase Wires

The motor uses 6mm² high-current phase wires, providing stable power output even under maximum load.
Paired with the heat sink, heat generation is reduced, allowing the motor to deliver stronger torque and consistent performance.

✔Premium Build Quality for Long-Term Durability

Pure copper windings for higher efficiency and better heat resistance
Strong aluminum alloy housing + external cooling cover for optimal heat dissipation
8-pole magnet design ensures quicker response, higher efficiency, and smoother power delivery.
The additional heat sink not only improves function but also protects the motor body from debris and impact.

✔Flexible Mounting & Reversible Drive Function

Available with or without mounting bracket, making installation easy on different frames.
Supports forward and reverse rotation — connect a reverse switch or reverse throttle to instantly change direction, ideal for Go-Karts and custom vehicles.

FAQ

What’s the difference between the 48V 2000W and 72V 3000W versions?

The 48V 2000W version offers balanced power and efficiency for daily riding and moderate load applications, while the 72V 3000W version delivers higher output and stronger torque for speed‑focused builds and heavy‑load projects. Both share the same robust brushless architecture and advanced heat‑dissipation design.

What vehicles is this motor compatible with?

This motor is compatible with electric dirt bikes, electric go‑karts, mini motorcycles, e‑scooters, e‑bikes, mopeds, and DIY electric builds. It also works with common controllers such as Kelly and FarDriver models.

Does the motor include thermal protection?

Yes. This motor features a built‑in KTY83‑120 temperature sensor and an external aluminum heat sink that enhances cooling and prevents overheating during prolonged or high‑load use. Programmable controllers enable setting thermal thresholds for added protection.

What kind of performance can I expect (speed/torque)?

Performance varies by voltage and load, but higher voltage (e.g., 72V) generally results in higher top speeds and torque compared to lower voltage systems. For example, 72V brushless motors with sufficient controller capacity can help vehicles reach speeds above 35 mph depending on wheel size, rider weight, and terrain.

Can I reverse the motor direction?

Yes. The motor supports both forward and reverse rotation. Simply connect a reverse switch or install a reverse throttle on your controller for easy directional changes — ideal for go‑kart or custom vehicle applications.

How do I choose the right controller for this motor?

Choose a compatible brushless DC controller rated for the motor’s voltage and current requirements (e.g., 48V for 2000W or 72V for 3000W). Controllers with adequate MOSFET capacity and programmable features (like thermal cutoff or current limits) help optimize performance and safety.

What battery voltage should I use for best performance?

Use a 48V battery system for solid, balanced performance and efficiency. A 72V battery pack paired with the 3000W version generally delivers higher speed and stronger torque, though battery capacity, controller efficiency, and weight all affect overall performance.

How does the heat sink improve performance?

The external aluminum heat sink increases surface area for better heat dissipation — reducing thermal buildup during extended riding or heavy loads. This helps sustain performance, protect internal components, and extend service life.
