The invention discloses an escalator braking method and device. The escalator braking method comprises the steps that S1, a speed measuring sensor detects gear pulses; s2, the main board receives the pulse and controls a frequency converter; and S3, the frequency converter controls the motor to achieve escalator braking, the device matched with the method comprises a main board and the motor, the frequency converter and a speed measuring sensor are arranged between the main board and the motor, the frequency converter and the speed measuring sensor are both connected with the main board, the motor is connected with the frequency converter, and the speed measuring sensor is connected with the frequency converter. The frequency converter controls the rotor of the motor to cut the static magnetic field to generate the braking torque, the braking torque can be set and changed through the frequency converter, the situation that the escalator suddenly slides when the escalator stops can be dealt with, and accidents of personnel due to escalator sliding are avoided.
