●Hybrid linear stepping motor is a stepping motor that converts rotation into linear motion through a built-in screw
●The actuator uses a basic hybrid stepper motor design, and a step angle of 1.8 or 0.9 degrees is applied. There are three basic types of linear stepper motors—fixed shaft, through shaft or externally driven versions.
Captive Lead Screw Linear Actuator
●Fixed shaft motor uses its own spline as a guide device to achieve a maximum stroke of 63.5mm in linear motion.
Non-Captive Lead Screw Linear Actuator
●Although the synthetic motion is linear, the screw still rotates, and the anti-rotation device needs to be designed by the customer.
External Lead Screw Linear Actuators
●Nut moves linearly relative to the screw
●The anti-rotation device needs to be designed by the customer.
Our 1.8 or 0.9 degree motor drives an integrated threaded screw through the rotor magnet and threaded nut assembly to provide linear motion in the machine. Wheeler's hybrid linear stepping motor provides a size specification of 21 to 86mm and has different resolutions, the step length is from 15 to 127um/step, and the linear force generated ranges from 1N to 2000N.
We are equipped with various precision screws with different leads and different pitches. According to the mechanical characteristics, the larger the lead, the lower the thrust, but the transmission speed is fast. The smaller the lead, the greater the thrust, but the transmission speed is slow.
Our nuts are made of special materials, which have good wear resistance, high lubrication, low friction, and high physical stability.
The closeness between the actual value and the theoretical value.
Due to manufacturing tolerances between individual parts in production, there will be slight differences in actual strokes. High-precision products make this error very small. However, the error always exists. For example, the screw lead is 1 inch (25.4mm), and the theoretical linear stroke of 360-degree rotation is 1 inch, but the actual maximum of 1 inch The error may reach +1-.0005 inches.
Under certain conditions, the motor is commanded to the degree of consistency of the position range of the same target. For example: Let the linear stepping motor nut move a certain distance from the starting point, measure and record this distance, call it, and then let the actuator return to the starting point, let the linear stepping motor repeatedly walk to the command distance X, the actual value and X The difference is repeated positioning accuracy.
The motor uses specially configured high-performance grease, so that the motor no longer needs to be lubricated, and has outstanding durability. The working temperature range is -65℃~250℃, and it is not flammable.
●Because the error does not accumulate, good accuracy can be maintained regardless of whether it is a short stroke or a long stroke, which means that there is no need to use expensive position feedback devices, such as encoders. The motor can run in single-step, half-step, or micro-step mode, resulting in higher accuracy, greater power, and quieter operation.
●Excellent open loop control. No need for encoder, low cost, compact design
●The same power drive motor can maintain synchronization and maintenance-free
●Avoid complicated closed-loop control with suitable positioning accuracy, configurable unipolar and bipolar coils
●Using standard hybrid stepping motor size specifications to simplify integration
●The top of the screw rod has a thread for easy connection, and an adapter can be added to provide M2-M6 thread, which is convenient to match the load.
