Motor protection and control systems

Various malfunctions can occur in three-phase electric motors and their power supply circuits, which in turn can lead to both damage to the motor and electric shock to personnel.

Major malfunctions of electric motors

  • power failure;
  • exceeding the maximum allowable voltage;
  • phase loss;
  • no neutral;
  • phase sequence errors;
  • voltage asymmetry.

Automatic control and motor protection systems

Protection of the electric motor from these negative factors is provided by special circuit breakers and protection relays. All modern motor control devices also have a protection function: soft starters and frequency drives (frequency converters).

Motor protection by circuit breakers

Motor protection by circuit breakers ensures

  • motor short circuit protection;
  • excessive overcurrent.

Motor protection relay

Relays provide motor protection against:

  • phase loss;
  • undervoltage or overvoltage;
  • phase sequence violations.

Frequency converters

Frequency converters provide motor protection against:

  • short circuit at the output and to ground;
  • converter overheating;
  • overtorque at the motor shaft;

Motor soft starters

Basic functions of motor soft starters

Soft start

  • starting the motor with a given starting current limitation
  • starting the motor with a smooth increase in voltage
  • starting the engine with the initial torque “shift”

Soft stop

  • soft stop of the engine with a given intensity
  • dynamic braking

Motor protection by soft starters is provided from:

  • overcurrent;
  • phase loss;
  • short circuit and overheating.
