The R-09-150 CCWM Series of Counterclockwise, Forward Shaft Extension Rotary Solenoids from Magnetic Sensor Systems (MSS), available in OEM quantities, features 18 different winding configurations allowing the user to match torque and duty cycle requirements to an application. These compact 38.1 mm (1.50 in.) diameter solenoids are just 22.098 (22.1) mm (0.87 in.) long and have two M4X0.7 threaded studs (8-32 studs optional) 7.366 (7.4) mm (0.29 in.) long on a 22.225 (22.2) mm (0.875 in.) bolt circle. The shaft has 40 degrees of counterclockwise rotation, extending (13.0) mm (0.51 in.). The shaft end is serrated for a better grip of the attached load.
The Electrical Apparatus Service Association (EASA) announces its Spring 2023 training seminar schedule. Offered in various locations around the United States, EASA's industry-specific training pools more than 100 years of rotating equipment knowledge from EASA's technical support staff. Participants have an opportunity to interact face-to-face with the presenters, as well as each other.
This Oriental Motor article provides more information on these types of noises and what can be done to minimize the noise. It's important to remember to isolate the motor from any other noise-making source, such as metal plates or loose bolts. It's also very useful to have an extra motor in good working condition for noise comparison, so you have a reference point.
