Product Description
The HSR-1425CR is a special motor manufactured to operate as a continuous rotation servo. Dual ball bearings on the output shaft ensure long lasting performance. Essentially, it is a gear motor that can be controlled by an RC servo controller. It is not normally used as an actuator, as there is no way of commanding it to move to a particular position, as a standard RC servo does.
Normal servos can be adapted to continuous rotation use, but the problem is that the range of positions that result in the motor being stopped is very narrow. Continuous rotation servos, depending on the position commanded, can go forward or reverse at different speeds. With an adapted continuous rotation servo, the position range for the different speeds is very narrow, making it difficult to produce a specific speed.
The 3202 is superior because it has a very wide "deadband" so you can be sure the motor is stopped when you command it, and the position range for forward or reverse motion is very wide, giving lots of speed resolution.
RC servos are hobbyist remote control servos typically used in radio-controlled models, where they provide actuation for various mechanical systems such as the steering of a car, the flaps on a plane, or the rudder of a boat. These servos are not industrial grade and are not recommended for continuous heavy use.
Operation
The motor is stopped at Target Position 50 (the stopped position is actually a range that goes from 45 to 55 depending on your motor). When you change the target motor position to a value less than your motor "stop range" the motor will rotate counter-clockwise. When you change the target motor position to a value higher than your motor "stop range" the motor will rotate clockwise.
Speed is controlled by changing the motor target position. As you move further away from the "stop position" the motor will increase speed until it reaches maximum speed. Acceleration can be controlled by using the velocity property in the PhidgetAdvancedServo.
