A driving and resistance control system for a permanent-magnet synchronous motor is disclosed. A control device includes a processing unit, a motor driving circuit, a resistance controller, and an interlock switch. In a first operation mode, the interlock switch makes the motor driving circuit and the permanent-magnet synchronous motor open-circuiting, and connecting stator windings of the permanent-magnet synchronous motor to the resistance controller, and under this condition, the external rotor of the permanent-magnet synchronous motor is rotated by spinning of a flywheel, so that the permanent-magnet synchronous motor is operating in a generator mode to generate a resisting force to the flywheel by mesas of a resistance generation device. In a second operation mode, the interlock switch makes the motor driving circuit and the permanent-magnet synchronous motor closed-circuiting and cutting off control of the resistance controller, and electrical energy is supplied from the power supply circuit to the permanent-magnet synchronous motor, so as to make the permanent-magnet synchronous motor operating in a motor mode to induce an acceleration on the external rotor.

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetically induced force that introduces a force threshold that, in effect, provides a threshold to part movement and confers a degree of hysteresis, preventing movement until a sufficiently large energizing force is applied. The effect may be further altered by use of an additional magnetically induced force interaction with at least one further member to urge or slow movement once started and/or to prevent movement once a new position is reached.

A personal escape device includes a main housing, a shaft, a magnet housing, and a plurality of magnets. The shaft is rotatably coupled with the main housing and is rotatable about a rotational axis. The magnet housing is positioned in the main housing and is coupled with the shaft such that the magnet housing rotates together with the shaft. The plurality of magnets is coupled with the magnet housing such that the plurality of magnets rotates together with the magnet housing. The stator assembly is coupled with the main housing and surrounds the magnet housing. The stator assembly and the magnet housing are radially spaced from each other to define an air gap therebetween.
