- AC motor are applied for converting AV of 50 Hz into AV of adjustable value and frequency for power supply to induction and synchronous motors
- CEM ensures:
– Smooth start with the set current or start time;
– Adjustment and maintaining of the set rotation speed;
– Motor current limitation in static and dynamic modes.
- CEM includes the following components and units:
– Power unit;
– Automated adjustment, protection and alarm system;
– Exciter (synchronous motor);
– Input converter transformer or network reactor;
– Power commutation and protection devices in input /output circuits
– Output filter.
– Automatic diagnostic system for the motor components.
