A throttle is usually fitted into the motor’s inlet, although it can also be fitted into the exhaust.
The benefit of throttling the inlet is that air consumption is reduced, whereas throttling the exhaust air maintains a slightly higher starting torque.
When it is desirable to maintain a high starting torque but reduce running speed – throttling is the best method of modifying the motor’s output.
When using a pressure regulator it is always fitted into the inlet of the motor. The use of pressure regulation is ideal when control of the stall torque is required and a high starting torque unimportant.
