Stepper motor is a variety of types specifications, specifications different types of specific aspects of the applicable and can this kind of motor in operation and function of performance will be different, but no matter what you use the types and specifications of the motor, should be before you start the motor so check the structure, through the check the motor is not bad problems, ensure the motor structure is completely normal, to be able to start the motor running use: check whether there is any crack on motor appearance: before the start of the stepper motor to check appearance, namely containment structure parts, whether appearance can see obvious crack, if found that the crack should be handled in a timely manner, cannot be used in the presence of cracks of the motor appearance condition. Confirm all fastening screws and parts are complete, before you start the stepper motor, everyone should pay attention to the motor of the fastening screws and parts inspection, whether these parts is complete, if found to have missing parts, to make up for all the applicable parts in time. Observe whether fixed condition of the motor is good: before you start the stepper motor, you need to pay attention to observe motor fixed position, ensure its fixed in good condition, the whole structure in a stable and secure condition. In order to ensure that after the start of step motor can run normally, safely use, request everybody before starting to check the structure of the motor. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
