Stepping Motor must face the problem of waterproof and moisture-proof
The stepping motor must face the problem of waterproof and moisture-proof. Recently, some customers asked the stepping motor manufacturer Rui Te Xiaobian how to prevent moisture in this stepping motor, and whether the stepping motor needs moisture-proof, today, I 'd like to talk to you about this topic. Stepping motors need moisture prevention. Stepping motors are open-loop control elements that convert electrical pulse signals into angular displacement or linear displacement.
In the case of non-overload, the rotation speed and stop direction of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by load changes, I . e. adding a pulse signal to the motor, the motor turns over a step angle.
The existence of this linear relationship, coupled with the characteristics of stepper motors as long as periodic errors and no cumulative errors.
It makes it very simple to use the stepping motor to control the speed, orientation and other control areas.
Waterproof is no longer a new topic. Whether it is a tunnel, a bridge, a embankment, a road, a building or a house where we live everyday, waterproof cannot be ignored.
At the same time, the electrical products used in our daily life also have the problem of waterproof and moisture-proof that must be faced directly.
The driving power supply of stepping motor consists of variable frequency pulse signal source, pulse distributor and pulse amplifier, thereby the driving power supply supplies pulse current to the motor winding.
The operation function of stepping motor depends on the outstanding cooperation between motor and driving power supply.
The advantages of the stepping motor are no accumulated errors, simple structure, convenient operation and maintenance, low manufacturing cost, and the ability of the stepping motor to drive the load inertia is large, which is suitable for small and medium-sized machine tools and places with low speed accuracy requirements, the defect is that the power is low, the heat is large, and sometimes'Out of step'.
