24VDC Brushless Motor Electric Actuator Modulating Valve

DC 24V Brushless Motor CZPT Actuator Attribute

one.Optimal Motor Features

The rotating pace of DC 24V brushless motor is in proportional to voltage and inversely proportional to output torque which is proportional to present.

2.Permanent Magnet rotor has no fever phenomenon

The complete established temperature growing is about twenty degree reduced in comparison with AC motor. Regularly start off-up will not likely cause motor and drive circuit fever and it can meet up with the requirement of open and near frequency more than one,two hundred instances for every hour.

3.Large CZPTt-up torque and powerful overload ability

Whilst actuator opening the valve,the motor rotating speed begins from minimal assortment and steadily speed up to standard pace and therefore lowered the start off-up recent (no more than rated current) and the influence will come from mechanical driving products when actuator begins-up ,that effectively lengthen the existence of actuator and keep away from the “Drinking water Hammer” phenomenon which can occur in the pipe with liquid medium.

four.Versatile open and close purpose

When actuator is running in open up or near position and valve opening degree is close to the established worth, the handle circuit will immediately sluggish down the rotating pace of motor and efficiently minimize down the rotating inertia of motor and increase positioning precision, also lessen the effect of valve and mechanical generate unit even though positioning.

5. Reverse electromagnetic brake purpose

when actuator is positioning the established opening position, Taking into consideration the characteristic of brushless motor and control circuit , it can simply attain reverse electromagnetic brake and enormously enhance the positioning accuracy (mistake no much more than±0.1%) by coordinating with flexible shut operate and obtain non- concussion orientation which indicates damping attribute is zero. Simply because this type of brake is non-mechanical friction, so that result can stay in extended-expression security.
six. Torque take a look at handle & in excess of-torque protection
Since Electromagnetic torque of brushless motor only link with existing as a result CZPT actuator can precisely and stably realize the torque examination handle and above-torque safety.
7. Instantly low velocity and large torque push CZPT perform
Sometimes valve may occur”Jamming”phenomenon because of to variables this sort of as uneven thermal growth or Eccentric instant and other influences.
“Jamming”:The torque that valve necessary in specific open place or open up district is bigger than regular price.
When it transpires the actuator will instantly reversely back up a little bit, then with lower velocity and large torque to drive CZPT until finally “Jamming “phenomenon disappeared and then automaticallyreturn to normal velocity and torque.
