    Brushless motor power supply units for FA equipment and industrial equipment

    For Power Supplies Brushless motor power supply units for FA equipment and industrial equipment

    This page introduces problems that often occur with power supply units of brushless motors for FA equipment and industrial electrical equipment, its mechanism, and the solutions.

    Noise problems that often occur with power supply units of brushless motors for FA equipment and industrial electrical equipment

    The conduction noise from the inverter and power circuit of the motor is too severe!

    Large current noises enter when there are lightning strikes! The equipment stops, or malfunctions occur!

    Murata's PLT10H solves these problems!

    How?

    Common mode choke coil in power supply lines of a 10A class which could not be done
    with a capacitor only using the PLT10H removes and suppresses noise!

    Reasons why PLT10H is effective at noise suppression

    • The PLT10H is very effective at preventing the inflow of noise that occurs in the inverter block, and the noise that flows in from DC input lines.
    • Compared to the common mode choke coils of other companies, the noise suppression of the PLT10H is more effective.
    • This is a hybrid type that suppresses both common mode noise and differential mode noise.

    Particularly, the combination shown in the following block diagram is the most effective for noise suppression.
