反射波现象的描述驱动器的逆变部分不产生正弦电压，而是由直流产生的一系列电压脉冲公共汽车。这些脉冲沿着电机电缆传到马达，然后反射回驱动器。反射是依赖于驱动输出电压、电缆特性、电缆长度和电机阻抗的上升时间。如果电压反射与另一个脉冲相结合，峰值电压可能处于破坏性的水平。一个IGBT驱动输出可能反映了两倍(2 pu或每单位)直流母线电压的波瞬态电压应力自己的输出线。多个驱动输出线在一个管道或金属托盘进一步增加输出线电压应力在多驱动器输出线之间的接触。驱动 1可能有一个(+)2 pu的压力，同时驱动器2可以同时有(-)2 pu应力。有关更多细节，请参阅PWM驱动器的连接和接地指南，发布驱动- in001。

1321-3R, 1321-3RA, and 1321-3RB Series Line Reactors

Applying Allen-Bradley Line Reactors

At the Input of the Drive

At the input of a drive, line reactors help protect against surges or spikes on the

incoming power lines and help reduce harmonic distortion.

At the Output of the Drive

In long motor lead applications, Allen-Bradley load reactors located between the

drive and motor help reduce dv/dt and motor terminal peak voltages. The use of

a load reactor also helps protect the drive from surge currents caused by rapid

changes in the load.

With Multiple Drives

Multiple drives on a common power line should each have their own line

reactor. Individual line reactors provide filtering between each drive to help

reduce any crosstalk while providing optimum surge protection for each drive.

With Multiple Motors

When more than one motor is controlled by a single drive, a single line reactor

can typically be used between the drive and all the motors. Size the line reactor

based on the total motor/load horsepower.

With Single-Phase Input

A three-phase reactor can be used for single-phase applications by routing each

of the two input power conductors to the outside two coils, and leaving the

center coil disconnected. The sum of the inductance of the two coils is the total

inductance applied to the circuit. Contact Rockwell Automation Technical

1321 Reflective Wave Reduction (RWR) Devices

Description of Reflected Wave Phenomenon

The inverter section of a drive does not produce sinusoidal voltage, but rather a series of voltage pulses created from the DC

bus. These pulses travel down the motor cables to the motor and then reflected back to the drive. The reflection is

dependant on the rise time of the drive output voltage, cable characteristics, cable length and motor impedance. If the

voltage reflection is combined with another subsequent pulse, peak voltages can be at a destructive level. A single IGBT

drive output may have reflected wave transient voltage stresses of up to twice (2 pu or per unit) the DC bus voltage between

its own output wires. Multiple drive output wires in a single conduit or wire tray further increase output wire voltage stress

between multi-drive output wires that are touching. Drive #1 may have a (+) 2 pu stress while drive #2 may simultaneously

have a (–) 2 pu stress.
