Abstract: An anti-deformation mechanism for an axial rod motor comprising a base, two vertical fixing seats, two axial fixing seats, two axial screws, a stator and a mover arranged on the stator. The two vertical fixing seats are arranged on the base to support the stator vertically. The two axial fixing seats are arranged on the base and located outside the two vertical fixing seats. Each of the two axial fixing seats is provided with a fixing through hole for insertion of the axial screw. The stator is an elongated cylindrical rod and provided with an axial screw hole at each of two ends thereof to be screwed with the axial screws. Both ends of the stator are fixed by the vertical fixing seats and the axial screws, and synchronously, the two axial screws apply pull forces to the stator to prevent the bending deformation of the stator.

Abstract: An interlocking device for controlling clockwise and counterclockwise rotation of a motor is connected with a clockwise rotation module and a counterclockwise rotation module at both ends thereof to form a loop by cooperating with a power-supply terminal and an earth terminal. The clockwise rotation module includes a clockwise rotation trigger switch and a clockwise rotation relay. The counterclockwise rotation module includes a counterclockwise rotation trigger switch and a counterclockwise rotation relay. By such arrangements, the loop collision caused by mis-touch can be avoided by a cross connection of the clockwise and counterclockwise rotation relays with the clockwise and counterclockwise rotation trigger switches, thus preventing the man-made careless mistake and maintaining the smoothness of the operation.

Abstract: An extendable gantry comprises a base and an extendable transverse bridge mounted on the base. The extendable transverse bridge has an axial length greater than a width of the base.

Abstract: A preloading and flex resistant support board for a mechanical machine comprises a support board body and at least one preloading bar. The support board body is formed with at one preloading groove in the side subjected to the compressive stress. The preloading groove is provided with two resisting surfaces. The preloading bar is also provided with two resisting surfaces. The preloading bar is assembled in the preloading groove of the support board body by screw, so as to provide a balance between the preloading capacity produced by preloading bar to the support board body and the flexing stress produced by the support board body.

Abstract: A servo control apparatus for a linear motor comprises a position feedback device, a driver and a position compensating device that are connected with one another. The servo control apparatus is electrically connected to the linear motor. By such arrangements, it can not only improve the precision of the displacement of the linear motor, but also make the movement of the linear motor relatively smooth.

Abstract: A direct drive torque motor comprises: a body, a direct drive torque motor, a main shaft, a bearing assembly, a brake assembly, a cooling assembly, and a position-sensing assembly. The bearing assembly is used to position the main shaft in the direct drive torque motor and the body. The brake assembly is disposed between the body and the main shaft. The cooling assembly is located in the body to cool the torque motor. The position-sensing assembly is mounted on the body for sensing the rotation of the main shaft and then controls the drive of the direct drive torque motor. With above arrangements, the direct drive torque motor can be used on various machines that need to rotate to perform various angle control, rotation control and accuracy control, it can improve the life and the modular application of the product.

Abstract: A positive load alignment mechanism comprises a platform device in which are disposed a plurality of driving devices, movable devices and movable bearing platforms. The driving device is connected to the movable device, and the movable bearing platform firmly supports a movable platform of the platform device. The driving devices are used to drive the movable devices to perform the back-and forth or left-and-right or rotating movement, and the movable bearing platforms firmly support the movable platform. By such arrangements, it can achieve the objectives of high pressure resistance, simplified structure, high security, high accuracy and all-direction displacement.

Abstract: A method of designing a reluctance resolver, and the resolver comprises a stator and a rotor, and an exciting coil and two sets of outputting wires wind around the tooth portion of the stator. The designing method comprises the following steps: fixing relative position; calculating the turn ratio of the stator; winding the coil of the stator; and designing the resolver. And the resultant resolver can improve the precision of calculating the position of the motor rotor.

Abstract: A pneumatic cleaning module for a magnetic ruler of a position measurement system is combined with a displacement transducer of the position measurement system by a screw so that when the displacement transducer moves along the magnetic ruler, the pneumatic cleaning module implements a high-pressure air to remove swarf, dirt and impurities from a surface of the magnetic ruler.

Abstract: A synchronous actuator comprises a telescopic cylinder assembly having at least three pivotally connected cylinders, a drive assembly and a driven assembly. The drive assembly is connected to two adjacent cylinders. The driven assembly is connected to three adjacent cylinders. With the drive assembly and the driven assembly, the cylinders of the telescopic cylinder assembly can be extended or retracted synchronously in axial direction.

Abstract: An origin microadjustment mechanism for a linear motor is assembled on a stator of the linear motor and comprises a load bearing member fixed to a sensing member and two positioning seats. The load bearing member is movably passed through the positioning seats, and the positioning seats are fixed to the stator, so as to adjust the position of the sensing member relative to the stator.

Abstract: A chain support structure for a planar motor comprises: a fixing base, a support arm and a load-bearing member, the fixing base is fixed to the stator, the support arm has one end connected to the fixing base and has the other end connected to the load-bearing member, respectively, and the load-bearing member supports the chain from the gravity direction of the chain the chain, so as to prevent the chain from the gravity-caused sag of the chain, and prevent the abrasion or damage caused by the chain rubbing against the stator.
