Abstract: A hub motor for a pedelec includes a hub housing, a shaft module, a stator unit including a control circuit board, a rotor unit, a freehub module, and a signal wire. The shaft module includes a shaft tube and a casing tube fitting around the shaft tube. The shaft tube has an inner circumference and an outer circumference, which are opposite, the inner circumference encircles to form a perforation. A groove is formed by recessing into the outer circumference. The casing tube fits around the shaft tube to cover the groove, thereby forming a wiring space. The freehub module includes a freehub body for sensing a rotational speed of the hub housing and an output portion electrically connected to the freehub body. The signal wire passes and is restricted in the wiring space, which prevents the signal wire from being torn. An end of the signal wire is electrically connected to the output portion, and the other end is electrically connected to the control circuit board.

Abstract: A hub motor includes an axle, a rotor, a stator, and a casing. The axle is fixed to a frame of a bicycle. The rotor is sleeved on the axle and pivots with the axle. The stator is fixed to the axle and adjacent to the rotor. The casing is sleeved on the axle and driven by the rotor to pivot with the axle. The casing has an accommodating space, a first perforation, and a second perforation. The accommodating space accommodates the stator and the rotor. The axle includes a first component and a second component. The first component is sleeved on the second component. The first component is arranged to pass through the first perforation. The second component is arranged to pass through the second perforation. The first component and the second component cannot rotate relative to each other after being sleeved.

Abstract: A hub motor includes an axle, a stator, a rotor, a casing, a sleeve, and a mounting seat. The axle has a first end, a second end, and a bump protruding out of a radial-outer-side surface of the axle. The bump is located on a side close to the second end in the extension direction. The stator is fixed to the axle and is close to the first end. The rotor is sleeved on the axle and pivots around the stator with the axle as an axis. The casing is sleeved on the axle, is driven by the rotor to pivot with the axle serving as an axis, and accommodates the stator and the rotor. The sleeve is rotatably sleeved on the second end of the axle and is connected to the casing. The mounting seat is connected to the axle and sleeved on the bump.
