The AC variable-frequency motor, together with the Hande digital vector variable-frequency control system, is described as achieving full-process automation and high operational performance.
The flyer prints a rated-power band of 400 to 4,500 kW, a rated-voltage band of 400 to 6,000 V, and a rated-speed band of 660 to 1,000 rpm, across 12 models. YJ-800B is printed at 550 V, inside that voltage band. The motors overview also prints a family scope of 600 to 4,500 kW for AC motors. The table includes the 400 kW row.
Performance
- Excellent speed-control performance, high output torque, and low starting current
