Shenyang Xingshun Lighting City has been in the past six months since its preparations last year. On July 28th, Shenyang Xingshun Lighting City will hold a trial operation. At present, the preparations for Xingshun Lighting City are in full swing.
Xingshun Lighting City is located in the core of Shenyang's largest home business district. It is jointly built by Wenzhou Developer, Wenzhou Shenyang Chamber of Commerce, China Lighting Association and Shenyang Jiangcheng Real Estate. It is surrounded by China Furniture City, Taolinju and Northeast Building Materials City. With a construction area of ​​40,000 square meters, it is the largest exhibition of the first-class lamps and lanterns in the Northeast, with the highest scale, standardized operation and excellent service. It is a wholesale and retail base and an information distribution center.
So far, all the shops in the mall are under intense renovation, and strive to provide consumers with a good shopping environment before the trial operation on July 28. Shenyang Xingshun Lighting City is another large-scale lighting city in Shenyang after Zhangshi Lighting City. At that time, consumers can not only purchase more professional products, but also experience the culture and art of lamps while consuming.

Advantages of Permanent Magnet DC Motor or PMDC Motor
PMDC motor have some advantages over other types of DC motors. They are :
- No need of field excitation arrangement.
- No input power in consumed for excitation which improve efficiency of DC motor.
- No field coil hence space for field coil is saved which reduces the overall size of the motor.
- Cheaper and economical for fractional kW rated applications.
Disadvantages of Permanent Magnet DC Motor or PMDC Motor
- In this case, the armature reaction of DC motor cannot be compensated hence the magnetic strength of the field may get weak due to demagnetizing effect armature reaction.
- There is also a chance of getting the poles permanently demagnetized (partial) due to excessive armature current during starting, reversal and overloading condition of the motor.
- Another major disadvantage of PMDC motor is that, the field in the air gap is fixed and limited and it cannot be controlled externally. Therefore, very efficient speed control of DC motor in this type of motor is difficult.
A spur gearbox could be either square type or round type as following:
According to the size of the gearbox, normally we have 12mm DC Spur Gear Motor, 25mm DC Spur Gear Motor, and 37Mm Dc Spur Gear Motor and so on.
DC Spur Gear Motor are relative simple in production, so the output efficiency is limited. According to the stages of the gear trains, the efficiency reduce one by one. However, the price would be a bit cheaper than other types DC Gear Motor .
