High-Performance AC Motor for Electric Golf Carts – 48V & 72V Options
Sun-Cart provides high-efficiency AC motors designed specifically for 2 to 8-seat electric golf carts and low-speed vehicles. Available in 48V and 72V configurations, our 5kW AC motors deliver high torque, ultra-quiet operation (<65dB), and zero brush maintenance – backed by a 1-year warranty.
Paired with our automotive-grade lithium iron phosphate (LiFePO₄) batteries, the system offers zero maintenance, IP67 waterproof rating, and no risk of thermal runaway — significantly safer than lead-acid or ternary lithium alternatives.
The electric motor is the heart of any electric golf cart — it determines acceleration, hill-climbing ability, energy efficiency, and overall reliability. Sun-Cart‘s AC induction motors are engineered for demanding commercial applications, from golf courses and resorts to industrial parks and beach patrol operations.
Unlike traditional DC motors that use carbon brushes requiring regular replacement, our AC motors are brushless — delivering higher efficiency, lower noise, and dramatically reduced maintenance. Every Sun-Cart motor is built by the same professional manufacturer that supplies Toyota, ensuring consistent quality and proven reliability.
Available in 48V and 72V configurations with power output from 3kW to 7.5kW, Sun-Cart AC motors provide the torque and durability needed for 2 to 8-passenger electric golf carts, utility vehicles, and custom applications.
Toyota Supplier Grade – Same Quality Standard
Our AC motor for electric golf carts is built by the same professional manufacturer that supplies Toyota. Same technology platform, same quality standards — proven reliability you can trust.
Zero Maintenance – No Brushes, No Wear Parts
Unlike DC motors, our brushless AC induction motor eliminates brush replacements. No carbon dust, no commutator wear — just reliable operation year after year.
Ultra-Quiet & Powerful – <65dB Operation
At less than 65 decibels, our 48V golf cart motor delivers whisper-quiet performance — perfect for resorts, golf courses, and noise-sensitive communities.
48V & 72V Options – Choose Your Power
Select 48V for standard efficiency or 72V for maximum torque on hilly terrain. Both configurations deliver 5kW of reliable power for 2 to 8-seat electric golf carts.
Regenerative Braking – Extends Range by 5-10%
Our electric golf cart motor recovers energy during deceleration, converting it back to the battery. Extends driving range by 5-10% — more trips per charge.
1-Year Warranty – US-Based Support
Every 5kW AC motor comes with a 1-year warranty. Our US-based support team provides technical assistance, remote diagnosis, and fast parts replacement.

Stator with Copper Windings
High-purity copper windings maximize conductivity and minimize energy loss. Precision-wound stators ensure consistent magnetic field generation for optimal torque output.
Permanent Magnet Rotor
High-grade magnets provide strong magnetic flux, contributing to the motor‘s high torque density and efficiency.
Precision Bearings
Heavy-duty sealed bearings withstand continuous operation and harsh environments, reducing friction and extending motor life.
Thermal Sensors
Built-in temperature sensors protect the motor from overheating, automatically reducing power output at 80°C and shutting down at 95°C to prevent damage.
Enclosed Housing
IP54-rated sealed housing protects internal components from dust, moisture, and salt spray — ideal for beach patrol and coastal applications.
