When looking for a speed reduced 3 phase motor at a particular RPM, several considerations should be addressed, Do you want the ability to control or vary the speed? Do you want only the fixed speed mentioned or something close? Do you want the shaft to come out the front of the motor, or out the right or left side? And very importantly is this a constant torque application, or is it a variable torque application. (An example of that would be, constant: a certain amount of weight could be on a conveyor belt and regardless of the speed, the motor has to do the same amount of work. Then we have to measure that work, Variable: fan balde is on a motor, and the slower the motor turns the less work it does.)
Once these questions have been addressed, then the reduced speed 3 phase motor question can be answered.
