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.
