The biggest difference between gear traction machine and gearless traction machine is that gear traction machine has gearbox and reduction mechanism, while gearless traction machine has no gearbox. In addition, the encoder with gear is relatively simple, and the encoder frequency converter without gear is more expensive, and the braking torque without gear is larger, while the torque with gear is generally smaller.

If there is nothing wrong with the gear, it will be easier to maintain. If you have a gear, you need to change the gear oil regularly, but if you don't have a gear, it will be very troublesome once it breaks down.
