Product features1 Safety
DYJ705 series belt driven elevator tractor adopts the imported customized V belt and the redundant design of many belts with the breaking safety coefficient of more than 10 which is much higher than that of drive train part of gear drive system. The tension of belt automatically increases with the increase of driver torque, and the belt will never slip no matter how high the tension is. So drive belt slipping problem is solved absolutely.2 High efficiency
Owing to the absolute elimination of drive belt slipping problem, almost all the power of motor is transmitted to the axle of traction wheel. Therefore, its comprehensive electromechanical efficiency is significantly higher than the low-speed permanent magnet synchronous gearless system and can save more property costs for users. Therefore, the lift tractor can make the power capacity of its corresponding drive inverter, contactor and other support equipment lower by at least one level.3 Anti-interference
The traction machine is equipped with the imported high-quality impact and electric magnetism resistant coder and adjusted and installed precisely with the patent technology to furthest eliminate the weak links of elevator system--the errors and faults of feedback system.4 Free-maintenance
The groove of drive pulley is processed elaborately; the allowable matching tolerance of drive belt and the allowable inclination angle errors beside the installation side of belt drive shaft are both ten times higher than the international standards; the drive belt tensions precisely’ the above four points can ensure the service life of more than 20 years of drive belt.The bearing is made of the special bearing steel with the special processes with the designed service life of more than 30 years. The refined processing, precise assembly, good lubricating and reliable sealing ensure the long-term operation of bearing under the precondition of no oil addition.The elevator tractor machine is equipped with redundant maglev caliper disc brake, its actuation and release don’t produce noises, the brake-releasing gap is adjustable, the friction surface trails automatically and the braking torque automatically compensates nonlinearly, so the brake doesn’t require maintenance and adjustment.5 Economical efficiency
The brake of the series Elevator Traction Machine installed on the low-speed axis and the electromechanical detection of speed limiter constitute the ascending car overspeed protection equipment which satisfies the ascending overspeed protection requirements of the newest EN81-1:1998, so the ascending overspeed protection equipment like ascending safety gear and rope brake. That greatly simplifies the safety configuration of elevator and saves considerable standards implementing costs for elevator producer.
