The invention relates to a motor used for a vehicle, a motor system comprising the motor and a charging and braking method adopting the motor system. The motor comprises a clutch unit, a planetary gear system, a rotor, magnetic steel and a stator fixedly connected with the magnetic steel, wherein the clutch unit is used for transmitting rotary moment between a wheel axle and the planetary gear system; the planetary gear system is arranged on the wheel axle in a sleeving manner, can utilize force transmitted by the clutch unit to drive the rotor to rotate, or can transmit rotation of the rotor to the clutch unit; when the vehicle travels normally, the motor charges a battery of the vehicle by utilizing induction current which is generated in a coil through relative motion of the stator and the rotor; when the vehicle receives a braking signal, the motor promotes the vehicle to brake by utilizing induction inverse potential which is generated in the coil through relative motion of the stator and the rotor. The motor has the characteristics of compact structure and simple maintenance.

The invention discloses a distribution line pay-off device with the braking function. The device comprises a pay-off rack, the pay-off rack is provided with a pay-off shaft in a rotating mode, a pay-off spool is fixed to the pay-off shaft, the pay-off shaft is fixedly connected to a rotating handle, and the pay-off rack is provided with a braking device braking the pay-off spool rotating inertially. According to the device, the braking device is arranged, by turning a braking control knob to rotate, a braking rod is driven to move axially, a braking contact surface between the braking rod and the pay-off spool is contacted so that the pay-off spool can be braked, the structure is simple and braking is convenient; and a wire arrangement device is arranged so that wires wound around the pay-off spool can be orderly arranged, the structure is simple, and the wire arrangement is convenient.

The invention provides a gear swing-arm single-motor jig dyeing machine which relates to a jig dyeing machine in the technical field of weaving and dyeing machines. The invention aims at designing a novel transmission mechanism with the characteristics of simpler structure, device matched investment reduction, motor power reduction, energy saving, stable operation, convenient maintenance, and thelike. Disclosed by adopting a picture 2, a main-drive swing gear 13 is arranged at the upper end of a transmission supporting arm 4, a passive large gear 7 is respectively arranged on one end shafts of a left and a right cloth roller 10, and an air cylinder 3 is connected with the transmission supporting arm 4, has an action of towing an extension function and is in tight contact with the passivelarge gears 7 arranged on the left and right cloth rollers 10. When the right cloth roller 10 reversely operates, the air cylinder 3 has the actions of automatically towing the extension function, isin tight contact with the passive large gear 7 arranged on the right cloth roller 10 and realizes the repeated alternating operation function of the left and right cloth rollers 10. The gear swing-arm single-motor jig dyeing machine is characterized by reducing power of an electric motor 1 and the matched investment of one electric motor 1 and one speed reducer 2, obviously saving electric energyand smoothly operating and can be quickly operated. Owing to the adoption of a novel transmission structure, the structure of the device is more simple and compact, the manufacturing cost of the device is reduced, and more importantly, the gear swing-arm single-motor jig dyeing machine is capable of saving large numbers of energy sources, reducing production cost and increasing economic benefit for users.

A brake assembly of a mute tubular motor is installed on the tail portion of the tubular motor and comprises a brake disk, brake pads, a fixing base, an armature base, a spring, an electromagnet and a brake cover. The brake cover is meshed with a shell of the tubular motor through teeth, the brake disk is fixed to a rotary shaft of the tubular motor, the brake pads are arranged around the periphery of the brake disk, the spring is installed in a spring groove in the center of the electromagnet, the fixing base is meshed with the inner wall of the brake cover through teeth, one side of the armature base makes contact with the spring, and the spring keeps applying push force to the armature base. A sliding shaft is arranged in the center of the armature base, and the sliding shaft penetrates through a positioning hole of the fixing base. Multiple sets of splayed oblique shafts are arranged on the armature base, and the oblique shafts penetrate through kidney-shaped holes in the fixing base and stretch into oblique holes in the brake pads. The brake assembly is simple in structure and easy to machine; the tubular motor is braked sensitively by a control circuit in the mode that the electromagnet is attracted to the armature base, and the brake pads are further controlled to be unfolded and tightened up through the oblique shafts. Friction plates of the brake assembly are abraded in an integral contact mode, the friction degrees in all positions are the same, and therefore the brake assembly is good in braking effect, longer in service life and low in noise.
