Understand Motor/System Baselines

Fri, 06/16/2017 - 10:06 -- Decatur Industr...

According to EASA’s technical experts, changes in motor/system vibration readings provide the best early warning of developing problems in a motor or system component. Other parameters to monitor may include operating temperature of critical components, mechanical tolerances, and overall system performance, including outputs such as flow rate, tonnage, and volume.

Motor-specific baselines incorporate records of electrical, mechanical, and vibration tests performed when units are placed in operation or before they’re put in storage. Ideally, baselines would be obtained for all new, repaired, and in situ motors, but this may not be practical for some applications. These baselines typically include some or all of the following:

DECATUR – Decatur Industrial Electric is pleased to announce Cole Namken has joined the company as plant manager.

Namken is a native of South Dakota, graduating from South Dakota State University and then entering the U.S. Army where he served in the United States and abroad. As an infantry officer and captain, he achieved many qualifications and earned several awards.

Namken was recruited by Caterpillar in Decatur, where he spent seven years in several manufacturing and engineering leadership positions. During that time, he attended Millikin University, receiving his master’s in business administration.

Most recently, he has worked in Decatur as a financial advisor. In his new role, Namken will be focusing primarily on operations, including production and efficiency.

 

DC Motor - Brush Arcing

Tue, 05/30/2017 - 11:24 -- Decatur Industr...

Our eyes looking through a commutator viewing window are still one of the best tools for identifying excessive arcing and sparking of the brushes on a DC motor. However, trending of the armature voltage in the time domain can provide an alternate visual tool in the detection of poor commutation and offset in the magnetic center. To see an example and read more about this technique please read:

Advanced Electric Motor is Heart of UPS Fuel Cell Delivery Truck

The Class 6 fuel cell delivery van UPS will begin testing late this summer using not only a unique hydrogen-powered electric drivetrain, but also an unusual type of electric motor.

Most electric-drive vehicles use motors that rely on permanent magnets and require single-speed “gear reduction” transmissions to harness the motor’s power.

UPS, however, has decided to try a “switched reluctance” motor that uses fewer parts and is less costly to manufacture than a permanent-magnet motor.

Additionally, a reluctance motor doesn’t need a transmission at all. Its power output can be regulated electronically through software designed to keep it operating in the most efficient modes under all types of loads, Michael Britt, head of UPS’ fuel cell vehicle development program, told Trucks.com.

“We think we can get more efficiency out of it,” Britt said.

The motor is manufactured by Nidec Motor Corp. to meet UPS’ specific needs. So-called reluctance motors typically are used for simpler applications than powering commercial trucks.
