Frequently Asked Questions
What makes 3820 the world's lightest high-speed motor?At only 172g, the 3820 delivers 22,000 RPM and 554W peak power while weighing less than a smartphone. This is achieved through advanced materials and optimized magnetic design.Is this motor suitable for 4-inch electric chain saws?Yes. The 3820 provides 22,000 RPM and 554W peak power, making it suitable for light to medium 4-inch chain saw applications. For heavier cutting, consider the 3823 Powerpack (700W).Can this motor be used for pull guns and riveting machines?Yes. The 3820's high speed (22,000 RPM) and bidirectional rotation make it ideal for pull gun and riveting machine applications requiring fast actuation.What is the difference between 3820 and 3823?3820: lighter (172g vs 350g), faster rated speed (16,000 vs 11,000 RPM) – better for lightweight pull guns and riveters. 3823: higher power (700W) and torque – better for heavy chain saws and grass cutters.Does the motor include a controller?The motor is sold separately. We can recommend compatible lightweight BLDC controllers for 12-42V configurations with stepless speed regulation.What is the expected motor lifetime?The 3820 is designed for long life with 2000+ hours rated operation under normal working conditions.
