7) The surface is fast cutting, pure metal bright, no painting
8) Brushless, Long life (bearing’s life), Free maintenance
10) Excellent starting, no magnetic hysteresis is damping energy consumption, Strong climbing capability
12) Superior water-proof
1) The motor should be kept in the dry and ventilated room, and should be free from moisture, acidic and alkaline . Please do not put the motor together with magnetic products.
2) The products shouldn’t be overloaded for long time ,the limited current of the controller should be less than 10A.
3) The motor should be free from water while it is working.
