D85L165 Waterproof Quanly 50kv 20kw Marine Electric Motor

 
Engineered for powerful and efficient electric marine propulsion, the D85L165-WP-50KV motor combines an advanced 12-slot 10-pole design with a compact 85mm diameter. Operating on a wide 14-38S voltage range (44.8-159.6V), it delivers substantial low-RPM thrust with a peak torque of 35 N·m and a maximum power output of 20 kW. Its fully potted and sealed construction achieves an IP68 rating, making it perfectly suited for direct-drive applications or integration into sealed units where permanent submersion and reliable performance are essential.
 
• Peak Power: 20.0 kW       • Peak Torque: 35.0 N·m      • Max Speed: 8,000 RPM
• Protection Rating: IP68     • Weight: 3.9 kg
