Stepper motor will gradually into the health care industry to be bestowed favor on newly

Stepper motor is a kind of electrical pulses into angular displacement of the actuator. Popular point: when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (i.e., step Angle). You can by controlling the pulse number to control the amount of angular displacement, so as to achieve the purpose of accurate positioning; At the same time you can control the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of regulating.

Who work in the medical device production any time all know, the machining accuracy is critical. In order to improve the efficiency and precision products, some of the OEM may consider to switch to the more expensive servo and stepper motor. Through to reassess what manufacturers need, from their expectations motor, medical manufacturers can rediscover and the darling of the motion control technology.

Step motor has been used in medical applications due to its powerful features, performance for decades, and overall value. Innovation, the step motor are put forward, rare earth magnets are used, and cause greater torque. In fact, today's stepping motor has more torque than their peers about 150% similar dimension 20 years ago. In addition, the processing technology has greatly improved, smaller motor manufacturing.

With strong magnet coupling, small stepper motor can do a bigger motor today. In addition to cause more save a space, in material and manufacturing process innovation has also led to higher efficiency motors. For most of the input power into heat and waste, high efficiency, the stepper motor only little energy waste and saving more money by reducing energy use, and able to work in a continuous cycle operation.

This work step, as in a smaller angular resolution higher as a result, the more the ability to make the motor stop in a given revolution. Instead of using the gear, a small motor interval Angle may be able to complete the application. There are two ways to reduce the step Angle. The first is that, by the electric driver. The second method is accomplished by increasing the machinery for motor phase number and/or the number of teeth. Step in such a way to reduce the pitch Angle increases the resolution, reduced vibration, reduce the error, and the cost, all because of a simple or half step driving can become less, rather than a micro step used in the drive.

The smaller the Angle of the stepper motor step now offers also eliminated the old stepper motor noise of motor, the motor is depend on when use point of view, a smaller interval Angle will make the motor vibration is less, lead to the application, in order to reduce noise.

Stepping motor in action

Review, some manufacturers a wide range of choice of medical applications of stepper motor made the difference.

Analyzer can have 50 axial movement, this depends on the process of upward. Stepper motor is because they can open loop operation of the fact that the obvious choice. To shut down of 50 axis circulation will be high cost. This machine is mainly used in the laboratory environment, therefore low audible noise is required. A 0.36 o step by step motor is because in low noise vibration transmission results perfect solution. In addition, the machine must comply with certain form factor. Because the appearance of various sizes, pony, can be used for shaft parts, reduce the overall size of the machine. Finally, the energy consumption and operation cost, high efficiency motor to reduce some or all of the shaft will be a good solution. Finally, XY sampling accuracy requirement is high, to ensure that the suction well. Stepper motor and mechanical high resolution by increasing the number of teeth is complete, has the best accuracy of various kinds of stepping motor.

Over the years, the function of the step motor makes their medical original equipment manufacturers of the best solution. They are not only easy to use, they are cost-effective, very accurate. Due to the designer and step motor manufacturers are constantly improve, they will continue to provide to ensure the motor by expanding its scope of functions, set out a new method, making them more powerful, more accurate, more efficient energy saving of medical makers the best solution.
