The invention discloses a wheel speed sensor, relates to the field of antiskid braking systems of wheel type take-off and landing aircrafts, and aims to solve the problems that when an aircraft brakes at a low speed, the amplitude of an output signal of the wheel speed sensor is small and the precision is insufficient. The wheel speed sensor comprises a wheel speed shaft, a rotor assembly and at least one stator assembly, each stator assembly sleeves the wheel speed shaft, the rotor assembly is in transmission connection with the wheel speed shaft, each stator assembly comprises a stator, the outer side wall of the stator is provided with at least one group of stator teeth, and the rotor assembly comprises a hollow rotor. Each group of stator teeth is opposite to the corresponding group of rotor teeth in position, and the distance between the tooth crests of the stator teeth and the central axis of the wheel speed shaft is smaller than the distance between the tooth crests of the rotor teeth and the central axis of the wheel speed shaft. The brake system comprises the wheel speed sensor. The wheel speed sensor, the braking system and the aircraft are used for improving the braking accuracy of the aircraft under the low-speed condition.
