China schrittmotor supplier can provide samples free of charge for customers with large or stable orders.The original linear motor for stepper motors used a combination of ball nut and screw.Ball screw improves efficiency by more than 90%, while trapezoidal screw provides only 20-70% efficiency, depending on thread conditions.Although the ball screw is an efficient method for converting rotational motion to linear motion, the ball nut requires high calibration and is bulky and expensive.Therefore, in most application fields, ball screw is not a practical solution.
Most equipment designers are familiar with linear motors based on hybrid stepper motors.The product has been around for many years and, like other devices, has its own strengths and limitations.Simple, compact and brushless in design, the obvious mechanical advantages, practical design, reliability are its inherent advantages, however, in some cases, this linear motor can not be used in some equipment, because it can not guarantee its durability without daily maintenance conditions.
