Our pancake shaped PM (permanent magnetic) dc motor has been developed for years by the company. It has a simplified structure, compact size, strong output torque, high energy efficiency (75% - 85%), high reliability and low noise. The PM used are powerful, decreasing cost rare earth magnets. The pancake motors can be widely used as the driving hub on electric bicycles, scooters, tricycles, battery powered vehicles and industrial motion solutions. Four voltage (12v/24v/36v/48V) models are available. Thanks to our innovative engineers on minimizing cost and maximizing performance with computer aided design and manufacturing techniques, today our factory is able to mass produce such motors at lowest cost to meet increasing demanding on personal and pollution-free electric transport products.

Useful Info:
Torque (in N*m) = 9.55 * Power (in watts) / Speed (in rpm)
1N*m = 141.61 oz*in = 8.85 lb*in = 10,200.0 g*cm, 1.0 hp = 745.7 watts
1.0 in = 2.54 cm, 1.0 kg = 2.205 lb = 35.27 oz, 1.0 mile = 1.61 Km
