Yaskawa U1000 Matrix Inverter

• Minimizes high-order harmonics and noise (less than 5% depending on the load).

• Capable of regenerating and feeding energy back to the grid directly without the need for dedicated devices.

• Improves the power factor (Cos Phi) to nearly 1 (Cos Phi = 0.98 or higher depending on the load).

• Enhances motor efficiency.

• Reduces costs for harmonic filters, reactive power compensation devices, and the installation and maintenance of such equipment.

• Lowers electricity costs due to:

  • Reduced energy consumption from harmonic filters, reactive power compensation devices, and AC-to-DC converters.

  • Regeneration and feedback of energy to the grid, helping save energy and minimize waste. Additionally, it reduces installation space by eliminating the need for resistive discharge or specialized grid discharge units, especially in applications involving regenerative braking.

The Yaskawa U1000 matrix inverter is widely used in various fields:

1. Cranes, Hoists, Bridge Cranes:
   With braking and reversing loads. The regenerative function optimizes energy recovery.

2. Elevators / Escalators:
   The regen feature helps recover energy during braking.

3. Inclined Conveyors:
   When materials move down the slope, braking energy is generated — the U1000 can regenerate electrical energy.

• No need for rectifiers and DC capacitors, making the system more compact, durable (no concern about capacitor aging), and energy-efficient with lower heat generation, leading to a longer lifespan.

• Reduces harmonic distortion, protecting other electrical equipment within the same system; no external filters are required.

• Regenerative braking: When the load is braking (e.g., an elevator descending, or a bridge crane lowering a load), energy is not wasted as heat but is fed back into the grid, resulting in significant energy savings.

• Allows torque and speed control in both rotation directions, making it ideal for applications that involve lifting and lowering, reversing direction, and frequent braking.

With its regenerative energy feedback capability, elimination of discharge resistors, reduction of harmonic distortion, and cost-saving operation, the Yaskawa U1000 Matrix Inverter represents a significant advancement in the current trend of green manufacturing and energy efficiency.
