The invention provides a fan and motor control all-in-one machine based on permanent magnet synchronous motor control. The fan and motor control all-in-one machine comprises a fan outer cover; a motor frame is bolted to the center of the back of the fan outer cover; a permanent magnet synchronous motor is bolted to an inner cavity of the motor frame through a mounting seat; a permanent magnet rotating mechanism is arranged in the inner cavity of the permanent magnet synchronous motor; and a fixing frame is rotationally connected to the centers of the two ends of the fan outer cover, and lifting columns are vertically connected to the two sides of the bottom of the fixing frame in a bolted mode. Through structural cooperation of a stator core, a stator winding and a permanent magnet rotor with cage bars, a rotating shaft can be driven to accurately and rapidly rotate, then the fan is driven to accurately and rapidly rotate, and the response speed of the fan is increased; and a push rod air cylinder provides a driving source, and through structural cooperation of a sliding sleeve, a sliding rail, a movable plate and a limiting pulley, the height of the fixing frame and the fan outer cover can be adjusted in a lifting mode, and the ventilation and heat dissipation effect of the fan is enhanced.
Description
technical field [0001] The invention relates to the field of fan motors, in particular to a fan motor control integrated machine based on permanent magnet synchronous motor control. Background technique [0002] The motor fan is a motor with a fan hub and blades. There are evenly distributed slots along the outer circumference of the fan hub. The blades are inserted in the slots. The blades and the fan hub are integrated by permanent connection methods such as welding and bonding. The motor The overall balance of the fan is good, which can save man-hours for adjusting the balance, and the weight is more than 30% lighter than that of the bolt-connected fan. [0003] Fan motors are used in many factory equipment, and most of the fan motors are integrated machines. However, during the use of the existing fan motor integrated machines, the fan cannot be precisely controlled based on the permanent magnet synchronous motor, which reduces the response speed of the fan. The height ...
