Brinkmann Sinus Motor
For over two decades Brinkman Turntables employed the highly-regarded German manufacturer Papst to supply Tape Capstan motors for use in our belt drive turntables. Technically and musically we had good results with this motor in combination on with our proprietary analog speed controller.
Helmut Brinkmann’s extensive research and development program, which resulted in the development of our bespoke, direct drive motor for the Oasis and Bardo turntables gave him valuable insight into the control of magne c elds and how to apply this knowledge to reduce cogging in a motor. The next logical step was to apply this knowledge to the design of a new motor for the belt drive turntables.
Compared to the Papst, Brinkmann’s new Sinus motor is be er suited to driving a high mass pla er like the
ones found in our Balance and Spyder turntables, because the use of 4-phase (4 mes 90°) drive circuitry—as opposed to the commonly used two-phase design used by Pabst and others--enab- les a much smoother rota on with reduced “cogging.” The arrangement of the driving coils and the neodymium magnets in combina on with the drive circuit achieves 12 “pulses” per revolu on. Addi onally the motor’s large rota ng mass of 500 grams, achieved by using a nickel-plated steel motor body, works likes a ywheel, thereby enhancing speed stability, driving the pla er of the turn- table with a very evenly distributed force and reduces vibra on.
The smooth and quiet rota on of our new, proprietary motor allows longer instrument sustains which results in more detail, resolu on and musicality. The virtually fric onless progression of the motor is readily audible in the e ortless ow of the music.
Our Sinus motor also generates more torque and is therefore able to reduce start-up me to a few seconds, which makes it an ideal match with the new (and op onal) RöNt vacuum tube power supply, which also enhances Brinkmann direct drive motors.
