(Before It's News)

Servo motors and Stepper Motors (Schrittmotoren) have some similarities and many differences. Generally speaking, stepper motors are controllable in measures without feedback whereas servo motors need a feedback device to make adjustments so. When you have a basic understanding of electricity and some ability using a millimetre troubleshooting both of these staples of industrial machines is not complex. An overall familiarity with their operation and motors and design is an added advantage as well. These daysstepper motors and servo motors, as well as DC Motors and Gearmotorsare available in almost every industrial environment. The intricacy of industrial machines and the modern controls which make them efficient typically feature a servo motor or stepper for some type of motion control. Human guided movement and gears, together with mechanical ratchets have always been replaced by these precision motors.

Before beginning any troubleshooting of industrial equipment, the care employees or the individual responsible for repair and troubleshooting should take all steps needed to ensure their own security and the security of those in the region of the machines. Suitable lockout, tagout, and confirmation that the machine is energy –free is the responsibility of everyone involved in the troubleshooting.
If the motor has failed using a few simple evaluations then you’re able to continue to determine once you have checked the remaining system is operating normally. If one is accessible these testcan be performed using a megohmmeter or a standard millimetre.First, disconnect and tag the motor cable. Each wire on the motor can subsequently be assessed for continuity to ground using a standard ohmmeter. Each wire should read infinite or at least 100,000 ohms at a minimum short to ground would suggest below that reading or a direct, anything a failed winding that is. Make sure to make a good clean connection on the motor cable and ground lug or case of the motor. Repeat this test with a megohmmeter is one is accessible.Motor containing brushes can be checked and the commutators cleaned when necessary. Brush dust can be carefully blown from a dirty motor using compressed air. This may even help ease a resistance reading to earth during the test that is short. The principles of servo motors and stepper motorsare substantially the same as conventional motors. Testing is, in addition, similar yet stepper or servo can occasionally intimidate maintenance tech or an experienced electrician.
