Servo drive power input interface structure and servo driverTechnical Field
The invention relates to the field of servo drivers, in particular to a servo driving power input interface structure and a servo driver.
Background
The servo driver is an important component of modern motion control and is widely applied to automation equipment such as industrial robots, numerical control machining centers and the like. Especially, the servo driver applied to control the alternating current permanent magnet synchronous motor has become a research hot spot at home and abroad. Current closed-loop control algorithms for current, speed and position based on vector control are commonly adopted in current alternating current servo driver design. The speed closed loop in the algorithm is reasonable or not, and plays a key role in the whole servo control system, particularly in the playing of the speed control performance.
The servo driver for large industrial equipment is generally huge, when the servo driver is installed, the top of the servo driver is often higher than the ground and even can be nearer to the top of a house, the power interface of the servo driver is generally arranged at the top of the equipment, the opening of the existing power interface is upward, the installation and inconvenience are caused, and particularly when the servo driver is fastened, a fastening tool is required to be fastened above the opening, the difficulty is high, and the installation time is wasted.
