Dynamos & Electric Motors
How to Make Them and Run Them

by Paul N Hasluck
reprinted by Lindsay Publications

Another gem from Hasluck's "Work" series from almost a hundred years ago.

Electricity was a cutting edge technology, but motors and generators (then called dynamos) were expensive. Here are a collection of articles from "Work" magazine of which Hasluck was editor describing how to build your own equipment.

Chapters include: the Siemens dynamo, the Gramme dynamo, the Manchester dynamo, the Simplex dynamo, calculating the size and amount of wire for small dynamos, ailments of small dynamo-electric machines, small electric motors without castings, how to determine the direction of rotation of a motor, how to make a shuttle-armature motor, fifty-watt undertype dynamo, and a four-hundred-and-forty-watt Manchester type dynamo.

Some of the motors and dynamos are small table-top machines which would make great experimental projects. You might be able to scale them up to generate significant power from a water wheel or windmill. Who knows? The 450 watt machine has interesting possibilities.

Lots of illustrations and details. Lots of information that can be adapted. Great lessons to be learned. Get a copy! 5-1/2 x 8-1/2 softcover 160 pages
