FAQ: Why are DC motor armature cores made of laminations?
DC motors are constructed with two major parts: the rotor and the stator. The rotor has a ring-shaped iron core with slots that hold coils, or windings. Following Farady’s law, when the core is rotated in a magnetic field, a voltage, or EMF, is induced in the coils. This induced EMF causes current to flow, […]
Engineering Big Challenges
Machines are designed to fulfill a purpose. That purpose is usually to solve a specific problem. In broad terms, machines convert input energy into motion to perform a task or produce a product. Machines are inanimate, even though they often exhibit motion through the use of mechanisms. Machinery is primarily about doing work, doing it […]
Overload protection for hard to reach drives
mayr power transmission’s EAS-reverse is a new, disengaging torque limiter on which all functional processes can be automated through the drive. It is easy to handle, permits long run-out times and re-engages again through slow backwards rotation. A housing also makes the clutch resistant to dust or spray water – and thus ideal for use […]

Cable Groups and Others Respond to FCC Chair Wheeler’s Departure
FCC Chairman Tom Wheeler’s announcement this week that he will depart the agency in January wasn’t exactly a surprise, but he did keep things interesting after the election by dodging questions about when or if he would step down. Reactions continue to stream in including the following from Michael Powell, president/CEO of NCTA, which given…
DeVry University Agrees to Pay $100M to Settle Federal Charges
For-profit DeVry University agreed Thursday to pay $100 million to settle federal charges that said it recruited prospective students with deceptive advertisements about the success of former students. The Federal Trade Commission said DeVry, a school with physical and online campuses, misled potential recruits with ads that cited false employment success rates and income levels for students…
Astronomers Detail New Method for Finding Stellar-Mass Black Holes
Stellar mass black holes are black holes formed by the gravitational collapse of massive stars. Astronomers at the University of Waterloo have developed a new method for identifying them. The improved black hole search method will bring the number of new stellar mass black holes discovered each year to 10, enough to double the number…
