When using it on electric bikes, carts, etc., for the required combination of traction and speed, you need to correctly calculate the ratio of the teeth on the drive and driven sprockets in the transmission, taking into account the diameter of the wheels - so that the traction increases in proportion to the increase in mass transport. The speed will then decrease.

  • For example, an electric bicycle equipped with such an engine accelerates to about 23 - 25 km / h. For three and four wheelers, the maximum speed will be lower.
  • When designing on your own, we first advise you to see if similar electric motors are used for similar vehicles, or if you should pay attention to other, more powerful models. We recommend consulting with our experts.
  • The electric motor, due to the built-in single-stage spur gearbox, has a low speed of rotation of the output shaft and good traction relative to its power. Sprocket on the shaft, suitable for a regular bicycle chain. This greatly simplifies the manufacture of the transmission and its repair, since we have bicycle chains and stars for sale.
  • When using driven sprockets with ratchet in the transmission, it is possible to implement free play (coasting).
  • During operation, attention should be paid to the temperature of the motor housing, which serves as an overload indicator. It should not exceed 80 degrees Celsius. If the engine is constantly running at high load and body temperature is close to the maximum allowable, this means that the engine is not selected correctly and it should be replaced with a more powerful model.
  • The closed housing prevents dust and moisture from entering the motor, thereby increasing the service life. The armature of the engine rotates in thrust bearings.
  • The gearbox, thrust bearings, commutator assembly and brushes are very durable. Brushes - do not require replacement, at least for several years of constant operation. The gearbox, bearings and manifold usually last much longer.
