Stepper motors which drive ways has both advantages and disadvantages
1. Constant voltage driver
single voltage drive is to point to in the working process of the motor winding, use only one direction for winding the power supply voltage, multiple winding alternating voltage. The way is a way of older drivers, basic need not now. Use this kind of drive, circuit is simple, less component, control is simple, implementation is simple. But it must provide enough current transistor for processing, the stepper planetary gear motor speed is lower, the motor vibration is larger, fever.
2. High and low voltage driver
due to the constant voltage driver has many shortcomings, the further development of technology, the development of new high and low voltage driver to improve the constant voltage driver part of faults, the principle of high and low voltage driver is, at the time of step motor movement to the whole using high pressure control, in the movement to the half step when using low pressure control, stop is also used in low pressure to control. High and low voltage control to a certain extent, improved the vibration and noise, the first time, puts forward the concept of subdivided control stepping motor, but also put forward to stop in half of the current work mode. But a relatively constant voltage driver circuit is complex, improve frequency characteristic of triode requirements, motor at low speed vibration is larger, still fever is still relatively large, now basically do not use this kind of drive mode.
3. Self-excited constant current chopper driver
the working principle of self-excited constant current chopper driver is when the current reaches a set value through hardware design through hardware will shut down the current, and then converted to electricity, another winding another winding electric current to a fixed current, but also through hardware to shut it down, so repeatedly, advancing step motor running. This greatly reduce noise, speed to some extent, raised, performance than the previous two have certain to improve. But for circuit design requirement is higher, the anti-jamming circuit requirement is higher, easy to cause high frequency, burn out driving element, the element performance requirements are higher.
4. Current compare chopping driver
current chopping driver is the stepper motor winding current value is converted into A certain percentage of the voltage, and D/A converter output of the default values are compared, the purpose of the comparison results to control winding current. Drive mode increase the movement control simulation of the sine wave characteristics, greatly improve the performance, speed and noise is small, can use higher segmentation, is the current popular control method. But the circuit is more complex, the circuit is difficult to control and the interference theory of consistent requirements, prone to jitter, formed in the control of sine wave peaks and troughs, easily lead to the high frequency interference, resulting in driving element fever or aging due to high frequency, which is easy to appear when a lot of drive to use more than a year the main reason for the red light protection.
5. Dive into type driving
this is a new kind of motion control technology, the technology is in the current under the premise of chopper drive technology, to overcome the shortcomings of these methods and innovation of a new driver. Its core technology is in the current chopping driver under the premise of increasing the driving element heating and high frequency suppression protection technology. But the price is quite high, at present each step motor and drive is relatively strict matching.
