悬浮门电机的选用原则
Selection principles of suspended door motors
1、功率选择：电机输出功率有限制。如果电机功率过小，负载超过电机额定输出功率，电机就会过载。过载时，电机会产*热、振动、转速下降、异响等现象。严重过载时会烧毁电机。
1.
Power selection: The motor output power is limited. If the motor power
is too small and the load exceeds the rated output power of the motor,
the motor will be overloaded. When overloaded, the motor will generate
heat, vibration, speed decrease, abnormal noise, and other phenomena.
Severe overload can burn out the motor.
2、选型：优先选用效率高、价格低、温升低的铁氧体悬浮门电机。
2.
Selection: Priority should be given to selecting ferrite suspension
door motors with high efficiency, low price, and low temperature rise.
3、规格选择：可根据实际需要选择扭规格，适当调整产品的电压和转速。
3.
Specification selection: Specifications with torque and speed close to
the corresponding rated value of the product can be selected according
to actual needs, and the required speed can be obtained by changing the
voltage; When the power supply voltage is fixed, if there is no suitable
product to choose from, the appropriate specification can be selected
based on torque, and the voltage and speed of the product can be
adjusted appropriately.
悬浮门电机使用规则
Rules for the use of suspended door motors
(1)如果悬浮门没有特别说明，一般情况下，悬浮门的电机是不允许在额定电压下反向运行的，否则会造成永磁体退磁；如果有需要进行这样的操作，应加限流电阻，限制过大电流。
(1)
If there is no special instruction for the suspension door, in general,
the motor of the suspension door is not allowed to run in reverse at
the rated voltage, otherwise it will cause demagnetization of the
permanent magnet; If such operation is necessary, a current limiting
resistor should be added to limit excessive current.
(2)在电机拆装过程中要注意过电流、温度变化、磁路开路等引起的永磁体退磁，特别是铝镍钴永磁电机，对永磁磁体应进行磁短路保护。电路在拆装时，否则退磁后需补磁。
(2)
During the disassembly and assembly process of the motor, attention
should be paid to the demagnetization of the permanent magnet caused by
overcurrent, temperature changes, open magnetic circuit, etc. Especially
for aluminum nickel cobalt permanent magnet motors, magnetic short
circuit protection should be provided for the permanent magnet. When
disassembling the circuit, it needs to be demagnetized before
