Where does the Cam go on a Ducati 1098?
Turning the rear wheel by hand, monitor the head assembly. The Vertical cyclinder Intake, opening at 15° Before TDC (of its INTAKE STAGE, not power stroke), cam starts to push down on the opening rocker arm.
How to check the bearings of an electric motor?
To perform a cursory check of the bearings, place the motor on a solid surface and place one hand on the top of the motor, spin the shaft/rotor with the other hand. Closely watch, feel, and listen for any indication of rubbing, scraping, or unevenness of the spinning rotor.
What’s the best way to check an electric motor?
Adjust the needle to 0 if possible. Locate a ground screw (often a green, hex head type) or any metal part of the frame (scrape away paint if needed to make good contact with metal) and press a test probe to this spot and the other test probe to each of the motor leads, one at a time.
How to check if an electric motor is drip proof?
Check that drip-proof motors are exposed to directed water spray or moisture, and that open motors aren’t exposed to any water or moisture at all.
When do you need to read a motor nameplate?
You will need information from the motor nameplate throughout the life of the motor. If you ever need to size a VFD, repair a motor, replace a motor, connect a motor, correct power factor, purchase parts, or do just about anything with a motor you will need the information on the motor nameplate. Horsepower is the mechanical output of a motor.
What does CT and VT mean on a motor nameplate?
CT stands for Constant Torque and VT stands for Variable Torque. If these ratings are on your motor nameplate it typically means your motor is rated for inverter use. Consult your manual for more information. Duty is the length of time a motor can run without a cooling period. Most industrial motors are rated for continuous duty.
To perform a cursory check of the bearings, place the motor on a solid surface and place one hand on the top of the motor, spin the shaft/rotor with the other hand. Closely watch, feel, and listen for any indication of rubbing, scraping, or unevenness of the spinning rotor.
How can you tell if a step motor is energized?
It can be noticed by turning a step motor by hand and is generally about one-tenth of the holding torque. In a typical one-phase step sequence for a two phase motor, phase A of a two-phase stator is energized (Step 1).
