The long box connected to the electric wheelchair mechanism is the deceleration mechanism, because the electric wheelchair uses a brushed motor, and the motor speed is about 3000 rpm, while the actual speed of the electric wheelchair is about 110 rpm, and the braking torque At 50Nm, a deceleration mechanism is required to decelerate and increase the torque. Therefore, the motor of the electric wheelchair is connected to the deceleration box, which is the reason for the power. The electric bicycle uses a brushless motor, and it requires fast speed and small braking torque. It looks small without a deceleration mechanism,
The power of the electric mechanism of the electric wheelchair is about 300W, and the power of the electric bicycle is about 100W.
Because the scope of use is different, the manufacturing cost is different, so the price is different.
The price of each electric mechanism of an electric wheelchair is about 800, and each electric bicycle motor is about 500.
