introduction:Torque motor working principle Torque motor is a kind of special motor with soft mechanical characteristics and wide speed range。The shaft of this motor does not output power at constant power but output power at constant torque。Torque motor includes:Dc torque motor、Ac torque motor、And brushless DC torque motor。 The main characteristic of torque motor is that it has soft mechanical characteristics,rotatable.When the load torque increases, the speed can be automatically reduced,At the same time increase the output torque.When the load torque is a certain value, the motor terminal voltage can be changed to speed regulation.But the speed adjustment rate is not good!Therefore, a speed measuring device is added to the motor shaft,Attach a controller.The voltage output by the speed measuring device is compared with the voltage given by the controller,To automatically adjust the end voltage of the motor.Stabilize the motor!

introduction:Rodless cylinder structure The ancestor of rodless cylinder is GermanyorigaPneumatic equipment Co. LTD,The rodless concept of cylinders was originally developed byorigaPut forward and practice,origaWith their own advanced technology research and development strength,Open the door to the rodless era。Rodless cylinder,Saves space for device integration。Rodless cylinder refers to the use of pistons directly or indirectly connected to the external actuator,And make it follow the piston to achieve reciprocating movement of the cylinder。The biggest advantage of this type of cylinder is that it saves installation space,Divided into magnetic couple rodless cylinder(Magnetic cylinder)With mechanical rodless cylinders。 Compared with pictures, text can often give people a clearer understanding of the general content,The following Xiaobian will take you to have a look!
