Does anyone make a 90 degree stepper or oscillator motor. Need
something that will swing 90 degrees at 90 Hz.

Yu best choice depends on the load to be moved and how long the
operating arm needs to be.

1. Stepper with proper control circuit
2. Servo (as in R/C car/plane) with proper control circuit
3. Reversible geared motor with limit switches
4. Geared motor driving eccentric/cam of proper design
5. push-pull solenoid (or pair of solenoids) moving one end of a
pivoted arm
