Embodiment Construction
[0011] Referring to Fig. 1, the present invention realizes the stopping distance requirement by increasing the speed of the flywheel. A transmission pair 3 is installed between the shaft end of the permanent magnet synchronous motor 1 and the flywheel 2, shown as a transmission chain 4, to increase the speed of the flywheel 2, and then increase the inertia of the flywheel 2 converted to the brake shaft, that is, the motor shaft. Use a working brake braking torque to achieve the required stopping distance.
[0012] What Figure 2 describes is that the delay braking of the additional brake is realized by a capacitor circuit. In additional brake Bk a A capacitor C is connected in parallel at both ends of the 4 , its anode and relay K 2 The normally closed contact is connected, the negative pole is connected with the inductance L 2 connect. When the speed of the escalator or moving walk exceeds the set value (less than 1.4 times the rated speed) or reverses, the control board ...
