Teardown of a 1952 Motorola transceiver’ power supply featuring a dynamotor.

Summary: This video examines a Carter Super Dynamotor from a 1952 Motorola transceiver and reviews its electrical and mechanical features. It also compares the input and output brushes and notes the associated transmitter tubes. Why This Matters: Dynamotors illustrate early methods for generating high voltage in mobile radio equipment. Understanding their brush structure and efficiency helps engineers appreciate the mechanical and electrical limits of these compact rotary converters. Content covered in the video: • Identification of the Carter Super Dynamotor and its intermittent-duty ratings • Review of the 5.8-V 75-A input and the 620-V 380-mA output • Calculation showing approximately 53 percent conversion efficiency • Inspection of input and output brushes and comparison of commutator segment widths • Evidence of mechanical damage and corrosion on the low-voltage section • Context from period transmitter tubes including the 807 and the 6146
