Several industries – including mining, steel, rail and power generation – rely on large motors equipped with commutators to produce the power required by their applications. However, without precision ...

Panacol has developed Vitralit ® UV E-2113, a new UV acrylic adhesive that is ideal for the rapid securing of commutators. This UV adhesive can be applied robotically and cures within seconds under UV ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

THOSE who are acquainted with Dr. Goldschmidt's writings will open this book with the expectation of finding a very intricate subject treated in clear and simple style, and this expectation will be ...

In this paper, we investigate some applications of commutator subgroups to homotopy groups and geometric groups. In particular, we show that the intersection subgroups of some canonical subgroups in ...

A minimal observable length is a common feature of theories that aim to merge quantum physics and gravity. Quantum mechanically, this concept is associated with a nonzero minimal uncertainty in ...

Preventive maintenance maximizes uptime while controlling costs. Maintenance crews strive to reduce maintenance costs and manage their workloads more effectively. Since DC machines require more ...

Journal of Operator Theory, Vol. 70, No. 1 (Summer 2013), pp. 109-144 (36 pages) We present a variant of Mourre's commutator theory. We apply it to prove the limiting absorption principle for ...

In the world of power tools, brushless motors are all the rage. While the technology isn't exactly new, it has gained traction in recent years due to some high-profile releases by Makita, Milwaukee, ...
