The introduction of Company.

Ningbo Lianjian has a production line of micro DC motor industry's most extensive, including brush DC motor, brushless DC motor.Through technical innovation and customer customization,assist you to create application system and rise above common herd.

         After many years of research and development, we have succeeded and truly for making the high quality, reliable and stable performance, with moisture proof,rust proof, high temperature resistance, high pressure resistance, high efficiency, prevent  deformation etc. The performance is close to maxon which is made in Switzerland, and passed the quality  requirements for medical equipment. 

The introduction of Coreless DC motor.
        Coreless motor applications, Micro drive solutions are  widely used in most of the industry and a lot of products. Requiring fast response servo system. Such as medical equipment, bionic prostheses,aerospace, automation, industrial robots, children's toys, Golf electric cars, video cameras(fast auto-focus), textile machinery, laser measuring instruments, high-magnification optical drive servo control,  Coreless motors can satisfy the technical requirements, the same one group power supply can be extended to more than double.

The main features of coreless DC motor:
1) Moisture proof, high temperature resistance, high pressure resistance,
2) No cogging effect.
3) To obtain high speedup with small inertia rotor.
4) Low electromagnetic interference
5) Low inductance
6) High efficiency
7) Linear voltage / speed curve
8) Linear load / speed curve
9) Linear load / Current curve
10) Design of commutator with multi piece, small torque fluctuation
11) Short time overload
12) Compact structure, small size
13) Can be matched with a plurality of gear box, encoder,DC tachometer.
14) Energy saving properties: The energy conversion efficiency is very high, its maximum efficiency in general is more than 70%, part model of the product can reach more than 90%(iron core motor general in 70%).
15) The control characteristics: start, rapid braking, fast response, mechanical time constant less than 28 milliseconds,part product can reach less than 10 milliseconds, some products can achieve less than 10 milliseconds(iron core motor generally in more than 100 ms).in recommended operating within the region of the state of high-speed operation ,  can be sensitive to regulate the speed easily.
16) Drag characteristics: The stability of operation is very reliable,speed fluctuation is very small, as micro motor, the fluctuation of speed can be easily controlled in less then 2%. in addition, the energy density of Coreless DC motor substantially improved. and compared with the iron core motor with the same power, its weight and size reduced 1/3-1/2
