There is no additional slip loss to change the pole pair speed regulation, and the efficiency is high; the control circuit is simple, easy to maintain, and the price is low; it can be combined with the stator voltage regulation or electromagnetic slip clutch to obtain smooth speed regulation with higher efficiency.

Stepless speed regulation cannot achieve stepless and smooth speed regulation. And due to the limitation of the motor structure and manufacturing process, usually only 2 to 3 kinds of pole pairs can be achieved, and the speed range is quite limited. Frequency conversion speed regulation has no additional slip loss, high efficiency, and wide speed regulation range; it can save electricity and protect the motor for long running time under low load or frequent start and stop occasions.

The technology is more complicated and the price is higher. The speed regulation of commutator motor has simple structure of AC synchronous motor and good speed regulation performance of DC motor; power supply voltage at low speed and back EMF natural commutation at high speed, reliable operation; no additional slip loss, Parallel Shaft Gearboxes high efficiency, and applicable It is suitable for the start and speed regulation of high-speed and large-capacity synchronous motors.

The overload capacity is low, and the original motor capacity cannot be fully utilized. Cascade speed regulation can feed back and utilize the slip energy generated in the speed regulation process. High efficiency; the capacity of the device is proportional to the speed adjustment range, and is suitable for 70%-95% speed adjustment.

The power factor is low, there is harmonic interference, and there is no braking torque during normal operation. It is suitable for loads that operate in single quadrants. The stator voltage and speed regulation circuit is simple, the device is small in size, and the price is cheap; it is convenient to use and maintain. The slip loss is increased during the speed regulation process.

It has the characteristics of power splitting and multi-tooth meshing. This angular displacement is the return gap. The whole machine has the characteristics of small structure size, large output torque, high Parallel Shaft Gearboxes Suppliers speed ratio, high efficiency, and safe and reliable performance.

This machine is mainly used for the slewing mechanism of tower cranes, and can also be used as a supporting component in lifting, excavation, transportation, construction and other industries. Servo motor reducer has small size, light weight, high carrying capacity, long service life, stable operation and low noise. Since one set of planetary gears cannot meet the larger transmission ratio, sometimes 2 or 3 sets are needed to meet the requirements of supporting larger transmission ratios. 　　

Return clearance: Fix the output end, and the input end rotates clockwise and counterclockwise, so that the input end produces rated torque +-2% torque, when it decelerates There is a slight angular displacement at the input end of the machine. It is also called backlash/backlash.Number of stages: the number of planetary gears. Servo motor reducer is a purpose A wide range of industrial products, whose performance is comparable to other military-grade reducer products, but at the price of industrial-grade products, are used in a wide range of industrial situations. New varieties of planetary series WGN fixed shaft transmission reducer, WN Sub-gear drive reducer, elastic even load and less tooth difference reducer.

The maximum input power can reach 104kW. Due to the increase in the number of planetary gears, the second level Or the length of the 3-stage reducer will increase, and the efficiency will decrease. The unit is 'minute', which is one sixtieth of a degree. The internal gear adopts 20CvMnT carburizing, quenching and gear grinding.　　

Servo motor reducer is a novel reducer with wide versatility. Suitable for industrial sectors such as lifting and transportation, construction machinery, metallurgy, mining, petrochemical, construction machinery, light industry and textiles, medical equipment, instruments, ships, weapons, aerospace and other industrial sectors
