Electric Powertrain innovation reaches new heights with the launch of SiAECOSYS's latest 5kW drivetrain solution, specially engineered for electric tricycles in urban delivery, cargo transport, and low-speed electric vehicle (LSEV) applications.

This complete powertrain package integrates a 5kW PMSM motor (with peak output of 10kW), a smart MCU (Motor Control Unit), and a customizable rear axle—delivering reliable performance, high torque, and exceptional energy efficiency for heavy-duty electric three-wheelers.

Key Features of the 5kW Electric Powertrain:

• Rated Power: 5kW (Peak 10kW)

• Voltage Range: 48V ~ 72V

• Speed Reduction Ratios: 8:1, 10:1, 11.87:1, 12.76:1, 15:1, 19:1 (Customizable)

• MCU Capabilities:

• CAN 2.0 Communication

• Programmable Functions

• Regenerative Braking

• Hill Start Assist (HSA)

• Anti-Slope Protection

The rear axle is designed for high strength and quiet operation, helping reduce noise while maintaining heavy-load capacity—making it ideal for commercial three-wheel EVs.

This electric tricycle drivetrain solution is optimized for manufacturers and fleet operators looking for durable, efficient, and intelligent low-speed EV systems.
