-主跟随器应用程序中连接的驱动器
如果电机必须以相同的速度/扭矩运行,则通常
以一种称为MASTER-FOLLOWER的方式控制。
用于此类系统的驱动器类型相同,可能在以下方面有所不同
但将由同一网络供电。他们的号码
通常不受限制。
从控制的角度来看,不同的条件和需求
需要匹配。
示例可从ABB自动化产品公司索取

根据机械配置,调试人员需要一些经验来相应地调整控制- Drives connected in Master-Follower application
If motors have to run with the same speed / torque they are often
controlled in a way called MASTER - FOLLOWER.
Drives used for such systems are of the same type and may differ in
power, but will be supplied from the same network. Their number
normally is not limited.
From the control point of view different conditions and demands
need to be matched.
Examples are available on request from ABB Automation Products
GmbH.
- Typical configuration for high power drives connected in
12-pulse parallel Master-Follower application
(see chapter 3.6)
This configuration shows a 12-pulse parallel drive system. It is an
easy option to increase the power of a drive system. Depending on
the engineering features , redundancy or emergency operation, if
one converter fails, is made available.
Such drives use two identical 6-pulse converters and an especially
designed choke called T-reactor or 12-pulse choke or interface
reactor. The converters are fed by a 12-pulse line transformer with
separated secondary windings whose phase positions differ by
30°el.
An example is the transformer configuration Ì/ /Ì. This
configuration gives a reduced level and a reduced order number of
harmonics on the AC side. Only the 11th and 13th, the 23rd and 25th,
the 35th a.s.o. are existing. The harmonics on the DC side are
reduced too, which gives a higher efficiency. (The field supply is not
shown on the wiring diagram 3.6. Depending on the field supply
selected, the connections to the network, the interlocking and the
control connections can be taken from any other wiring diagram
showing the selected field supply.)
It is not possible to connect two 12-pulse systems (2 converters, Treactor and 1 motor) to one 12-pulse transformer.
For more information, please see manual 12-pulse operation.
Figure 3/3: Application with two mechanically connected motors
- Typical configuration for high power drives connected in
Master-Follower application (two motors with one common
shaft)
This configuration is often used, if two motors have to share the
load half and half. They are mechanically fixed to each other via a
gearbox or any other device. The converters are fed by a 12-pulse
line transformer with separated secondary windings whose phase
positions differ by 30°el.
Each motor is connected to its own converter and field supply. The
converters exchange signals to make sure, that each motor takes half
of the load.
This configuration delivers the same advantages concerning harmonics to the network as a standard 12- pulse application (see next
item), but no T-reactor is needed.
Depending on the mechanical configuration commissioning personal needs some experience to adapt control accordingly
