Why Choose a Side-Mounted Motor?
Side-mounted motors (also called side-drive motors) offer unique benefits over hub motors or mid-drive motors, and the X155-36H amplifies these advantages:

1. Flexible Installation & Space Optimization
Unlike hub motors that integrate with the wheel or mid-drives that occupy frame space, this side-mounted design mounts externally to the wheel rim. It eliminates the need for complex drivetrain modifications, making it ideal for custom EV builds or retrofits. The compact layout also frees up frame space for larger batteries, extending ride range.

2. Balanced Weight Distribution
By mounting to the side of the wheel, the motor distributes weight evenly across the vehicle—preventing the “front-heavy” or “rear-heavy” issues common with other motor types. This balance enhances stability at high speeds (up to 70 kph) and improves handling on rough terrain.

3. Extreme Efficiency & Durability
· Hairpin Winding Technology: Boosts max efficiency to ≥93%, minimizing energy loss and extending battery life.
· Air Cooling System: Maintains optimal operating temperature during prolonged high-power use, preventing overheating.
· IP67 Waterproof Rating: Withstands rain, puddle splashes, and dust—suitable for urban commutes, off-road adventures, and commercial fleet use.
· Disc Brake Compatibility: Integrates seamlessly with disc brake systems for reliable stopping power, critical for high-speed EVs.

4. Test-Proven Performance
Under 72V 180A DC testing, the X155-36H delivers impressive results:
Maximum output power of 10352W at 749 rpm.
Peak torque of 333.3N.m, validating its hill-climbing and load-carrying capabilities.
Consistent efficiency across voltage and current ranges, ensuring reliable performance in real-world conditions.

Recommended Controller & Compatibility
For optimal performance, pair the X155-36H with the Fardriver ND72360B Encoder Controller (rated 72V, 360A peak phase current, IP67 waterproof). This controller is specifically tuned to match the motor’s power characteristics, enabling precise torque control, smooth acceleration, and enhanced safety protections.

The X155-36H side-mounted motor is perfect for:
· High-performance e-scooters and light e-motorcycles.
· Custom EV builds and retrofits (requires minimal frame modifications).
· Commercial fleets (e.g., delivery scooters) needing durable, high-torque motors.
· Enthusiasts seeking speed (70 kph) and power (13000W peak) for recreational use.

The QSMOTOR X155-36H redefines side-mounted motor performance with its hairpin winding efficiency, extreme power output, and rugged design.
Whether you’re building a custom e-motorcycle, upgrading a fleet of e-scooters, or seeking a reliable motor for off-road adventures, this model delivers on every front—flexibility, power, and durability.
