Which motor is better for the flat face mask machine?

The most popular mechanical equipment at the moment must be the flat face mask machine. The face mask machine on the market is usually made of aluminum alloy, which can effectively prevent oxidation and is easy to clean and maintain. However, many buyers often ignore the motor of the flat mask machine when purchasing the flat mask machine. It should be noted that the motor is the heart of the flat mask machine. Once a problem occurs, it will affect the entire mask manufacturing line.


There are many types of motors. Which motor is better for flat face mask machines? Strong H Machinery Manufacturing Co., Ltd. provides you with answers.

The flat mask machine


There are currently two types of motors equipped with mask machines on the market. One is equipped with a full AC servo motor, and the other is equipped with a stepper motor. The difference between the two is as follows:


1. Different low frequency characteristics. Stepping motors are prone to low-frequency vibration at low speeds. The vibration frequency is related to the load condition and the performance of the drive. It is generally considered that the vibration frequency is half of the no-load take-off frequency of the motor. This low-frequency vibration phenomenon determined by the working principle of the stepper motor is very unfavorable to the normal operation of the machine.


 When stepping motors work at low speeds, damping technology should generally be used to overcome low-frequency vibration phenomena, such as adding a damper to the motor, or using subdivision technology on the drive. The AC servo motor runs very smoothly and there is no vibration even at low speeds. The AC servo system has resonance suppression function, which can cover the lack of rigidity of the machine, and the internal frequency analysis function (FFT) of the system can detect the resonance point of the machine, which is convenient for system adjustment.


2. The moment-frequency characteristics are different. The output torque of a stepping motor decreases with the increase of the speed, and will drop sharply at a higher speed, so its maximum working speed is generally 300-600RPM. The AC servo motor has a constant torque output, that is, it can output a rated torque within its rated speed (generally 2000RPM or 3000RPM).


In summary, the full AC servo motor is more suitable for flat face mask machines. When purchasing face mask machines, please do not miss the attention to the motor. If you want to buy a high-quality flat mask machine, please contact Strong H Machinery Manufacturing Co., Ltd.!
