The working principle of ac servo motor with split-phase single-phase asynchronous motor, three phase induction motor though similar, but the rotor resistance of the former is much larger than the latter, diesel engine so compared with the single asynchronous motor, servo motor has three marked characteristics: 1, large starting torque. Due to the rotor resistance is big, the torque characteristic www.facebook.com/guohong.trading curve as shown in figure 3 in curve 1, with normal asynchronous motor torque characteristic curve, compared to 2 a significant difference between the two. It can make the critical slip S0 > 1, this not only makes the torque auto spare parts characteristic closer to linear mechanical properties, and has a large starting torque. Therefore, when the stator's a control voltage, rotor rotating immediately, which has the characteristics of starting fast, high sensitivity. 2, has a wide operating range. 3, no rotation.

The normal operation of the servo motor, as long ac synchronous generator as out of control voltage, the motor stop immediately. When servo motor loss control voltage, it is in single phase operation state, due to the rotor resistance is big, the rotation of single phase induction motor the two opposite diesel generator set directions in the stator rotating magnetic field and rotor effect produced by the two torque characteristics (T1, T2 S1 S2 curve) and synthetic torque characteristic (t-s curve) output power of the ac servo motor is 0.1 100 w. When the power supply frequency 50 hz, voltage is 36 v, 110 v, 220, 110 ac motor v; When the power supply frequency is 400 hz, the voltage have 20 v, 26 v, 36 v, 115 v, etc. Ac servo motor smooth operation, low noise. But control characteristic is nonlinear, and the rotor resistance is big, loss is big, efficiency is low, so compared with with the capacity of the dc servo motor, big volume, heavy weight, so is only applicable to 0.5 100 w small power control system.

The use of 60 hz import motor and power supply design

In the early 90 s, a rubber manufacturing company the five sets imported from North America (second-hand) rubber equipment, there are two production Farrell 11 d mixer and a SL sullair company - 32 type screw air compressor. Basic situation of the three electrical motor 12v 1000w devices test is good, according to the production requirements, companies need to benefit installation fan motor commissioning as soon as possible; But the use of these equipment there is a big technical problem: the driving gear of these devices is 60 hz five sets of high voltage motor, not directly into the 50 hz power grid of our country. But if all replacement for domestic 50 hz, 6 kv motors and high voltage, need to increase cost nearly 1 million yuan. In order to solve the technical problem, technical personnel for imported equipment of acmotortrading.blogspot.com the power supply system, switch gear, motor parameter and so on has carried on the earnest analysis and calculation, decided to adopt frequency conversion principle, tinkering with the system power supply design.

Germany Rexroth generator company or Rexroth Indramat division of MAC series ac servo motor with a total of seven frame # 92 specifications. auto spare parts Germany's Siemens (Siemens) IFT5 series three-phase permanent-magnet ac servo motor divided into two categories: standard and short type, a total of eight stand no. 98 kinds of specifications.

Choose fuse type and capacity, according to the protection of the load characteristics, the electric motors size of the short circuit current working conditions and use of the occasion. Most of the small and medium-sized generator price motor with light load or full pressure relief starting, starting current is diesel generator set usually 5 to 7 times of the rated current; The power capacity is larger, low-voltage distribution main transformer (including capacity) in 1000 ~ 400 kva, system impedance is small, when short-circuit fault occurs, the short circuit current is larger; The workplace such as kiln, grinding, poor ventilation condition, the working environment temperature is higher. Therefore, choose fuse breaking capacity and rated current of the melt, squirrel cage small diesel engine induction motor compared with the general industrial use should appropriately increase a bit.

Melt the experience formula of the rated current, melt rated current ac synchronous generator (A) = motor rated diesel generator set current (A) (3) the melt rated current simplified formula "melt protection, kw by 6". The simplified formula, is refers to A 380 v cage motors, light load starting or decompression starting full pressure, low operating frequency, suitable for below 90 kw and cage motor. If the actual use of the motor starting frequently, or starting time is long, the empirical formula or the simplified formula of the above results can be appropriately increased a little, but it should not be too large. In short to achieve when the motor starting, melt by fusing; In the case of acmotor2.blogspot.com short circuit fault, the melt must be reliable fuse, cut off power supply, to achieve the purpose of the short circuit protection.
