Nidec Corporation has acquired full ownership of TAR, LLC d/b/a Houma Armature Works, a privately- owned US company (“Houma”). As a result of the transaction, Houma became a consolidated subsidiary of Nidec.
Visitors to EASA in June will get a chance to see some of the highest efficiency electric motors available on the market when they stop by the Nidec Motor Corporation Booth (#613). Nidec’s “Super Premium” and above variable frequency drive (VFD) motors and all-in-one, integrated motors and controls are leading the industry with efficiency ratings of IE 4 and IE 5 for remarkable energy savings compared to traditional single speed motors.
SEW-Eurodrive is expanding its comprehensive portfolio to include new motors for purely inverter operation. The synchronous motors of the DR2C.. series satisfy the highest standard-based efficiency class IE5 for adjustable-speed electric motors. This makes them yet another sustainable and energy-saving motor variant.
ABB recently announced it has completed its acquisition of the Siemens low voltage NEMA motor business. The transaction was originally announced August 11, 2022, and financial terms of the transaction were not disclosed. The business employs around 600 people and generated revenues of approximately $63 million in 2021.
Portescap announces the release of the 45ECF brushless DC flat slotted motor, the latest addition to join our flat motor portfolio. The 45ECF features a performance optimized design that utilizes an outer rotor configuration with an overall diameter of 43.2 mm and a body length of only 22.5 mm. The motor features hall sensors to easily control speed and torque and can be provided sensorless based on application requirements. Additionally, the motor can be used in combination with existing gearbox designs to provide high output torque at required operational speeds.
Unlike HVAC applications, servomotors are not normally operated at the same speed or torque for extended periods, thus the overall efficiency of a servomotor is not easily given a single numeric value. The efficiency varies greatly with the application, and thus different applications favor different types of servomotors.
Orbex Group, a U.S.-based supplier of slip rings and electric motors, has introduced two new custom products to its offering of precision motion solutions. These custom flat brushless DC (BLDC) motors provide smooth motion, high precision and excellent power density, as well as an integral gear reducer in a compact package.
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.
