The load that the servomotor is used to drive should not exceed the maximum torque rating of the servomotor.
With Autoflame supplied valves, the correct servomotor size is already specified by Autoflame.
用于伺服电机驱动的负载不应超过伺服电机的最大扭力额定值。对于
Autoflame
提供的阀门，正确的伺服电机
尺寸已经由
Autoflame
指定。
To correctly size an Autoflame servomotors for use with a third party valves or dampers, the torque required
to drive that valve or damper should be checked, this in order to select a servomotor with sufficient torque to
drive the damper reliably.
Please check the manufacturer’s specifications for that valve or damper to check
the torque requirements.
为了正确确定与第三方阀门或风门一起使用的

伺服电机的尺寸，应该检查驱动该阀门

风门所需的扭
力，以便选择具有足够扭力的伺服电机来可靠地驱动伺服电机。请检查该阀门或风门的制造商的规格，以检查
扭力要求。
If this is unknown or the data is not available, then it is necessary to check the torque required to drive the
valve/damper using a torque meter. The torque should be measured when the valve/damper is fully loaded.
For example, for an air damper, that will be when the fan motor / VSD is driven at maximum speed. It is
recommended that a nominal 20% is added to the measured torque value to determine the type of servomotor
required for the application. This nominal 20% takes into account any factors such as dust, rust, and lack of
lubrication experienced between service intervals which can make the valve/damper require more torque.
如果这是未知的或数据不可用，则有必要使用扭力表检查驱动阀门

For example if the measured torque to drive an air damper at full load is 19Nm;
例如，如果测量的扭力驱动满载为

;
𝑆𝑒𝑟𝑣𝑜𝑚𝑜𝑡𝑜𝑟 𝑇𝑜𝑟𝑞𝑢𝑒 = 19 𝑥 1.2 = 22.8𝑁𝑚
伺服电机扭力
= 19 x 1.2=22.8Nm
Therefore a large servomotor may be selected for this damper.
因此，可以为风门选择大型伺服电机。
