Frequency Inverter for Concrete Mixer

The significance of using frequency inverter on concrete mixer is mainly in the energy consumption and stability improvement.

1. The energy-saving effect is remarkable.
After using the frequency inverter, the system saves more than 30% energy.

2. Improving the stability of the system, reducing the failure rate, reducing maintenance costs. This benefit is mainly reflected in the following aspects:

a. extension of life
The inverter drive enables the soft start of motor operation, thus avoiding the impact on electrical and mechanical equipment of the previous Y-Δ start. So the life of the equipment is extended.

b. powerful protection
The inverter control system has complete electrical protection function, including short circuit protection, overload protection, over-current protection, phase loss protection, under-voltage protection, etc, to maximize the safety factor of the motor.
