Forward and Reverse Operation of

Single-phase Inductive Motors

Motor

Note: 1. The voltage between the load terminals of either SSR 1 or

SSR 2 when turned OFF is approximately twice as high as

the supply voltage due to LC coupling. Be sure to use an

SSR model with a rated output voltage of at least twice the

supply voltage. For example, if the motor operates at a sup-

ply voltage of 100 VAC, the SSR must have an output volt-

age of 200 VAC or higher.

2. Make sure that there is a time lag of 30 ms or more to switch

over SW1 and SW2.

Forward and Reverse Operation of

Three-phase Inductive Motors

Wave-

form

Make sure that signals input into the individual SSRs are proper if the

SSRs are applied to the forward and reverse operation of a three-

phase motor. If SW1 and SW2 as shown in the following circuit dia-

gram are switched over simultaneously, a phase short-circuit will

result on the load side, which may damage the output elements of

the SSRs. This is because the SSR has a triac as an output element

that is turned ON until the load current becomes zero regardless of

the absence of input signals into the SSR. Therefore, make sure that

there is a time lag of 30 ms or more to switch over SW1 and SW2.

The SSR may be damaged due to phase short-circuiting if the SSR

malfunctions with noise in the input circuit of a SSR. To protect the

SSR from phase short-circuiting damage, a protective resistance R

may be inserted into the circuit.

The value of the protective resistance R must be determined accord-

ing to the withstanding inrush current of the SSR. For example, the

G3NA-220B withstands an inrush current of 220 A. The value of the

protective resistance R is obtained from the following.

R > 220 V x √2/200A = 1.4 Ω

Considering the circuit current and weld time, insert the protective

resistance into the side that reduces the current consumption.

Obtain the consumption power of the resistance from the following.

P = I²R x Safety factor

(I = Load current, R = Protective resistance, Safety factor = 3 to 5)
