Description
TYBVFT series explosion-proof permanent magnet synchronous variable frequency speed governing machine for mine is developed by our company based on accumulated years of experience in research and development and use of permanent magnet direct drive motors and servo controllers. New generation of driving power equipment. This device includes a low-speed permanent magnet direct drive motor and a special vector-type inverter. The appearance of this device will completely change the layout of traditional drives, eliminating the need for intermediate connection links and simplifying the complexity to further improve the load transmission efficiency.
Comparison of drive system configuration:
Compared with the traditional system, it is omitted: reducer, hydraulic coupler, motor, inverter, inverter chamber, output side reactance filter, and output cable.
All-in-one drive system: Permanent magnet synchronous frequency conversion speed control all-in-one machine (not affected by the output distance of the inverter, the equipment layout can be more willful)
Traditional drive equipment layout (equipment station + power distribution room)
All-in-one layout-driven layout
Equipment core advantages:
1. System integration solves the output distance limitation: focusing on technical pain points such as 1140 V inverter high du / dt and limited output distance. The all-in-one machine centralizes the inverter and the motor, completely eliminating the impact of the inverter's long-distance power supply voltage spike on the insulation life of the motor;
2. Reduce cable usage requirements and line interference: the all-in-one power supply does not need to shield the cable at all times, no need to consider radiation interference on the cable path, and the cable cost and laying cost are lower;
3. Simplify the drive configuration and system design work: The drive configuration is greatly simplified, greatly reducing the construction time and the construction workload. The device driver only needs to consider one device of the integrated machine;
4. The most advanced control algorithm: the third-generation permanent magnet synchronous vector control technology is used to give full play to the torque characteristics of the permanent magnet direct drive motor, and the starting capacity and overload capacity are further improved;
5. Optimized structural design: Designed with international advanced circuit topology to maximize power density;
