The HS-785HB winch servo with it’s large drum wheel has 8 revolutions of travel. With its dual ball bearing supported output shaft the HS-785HB will provide years of reliable service when used in RC applications.
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.
The 3201 – Winch Servo can be used with the following Phidget motor controllers:
You must, though, use the 1061 if you want to get the maximum torque out of your motor.
When testing the winch servo we found out that the motor will go into continuous rotation mode when provided with a target position outside its documented range. Target Positions between 2670 and 2730µs will produce clockwise rotation in increasing velocity and positions between 550 to 350µs will product counter-clockwise rotation in increasing velocity.
Set Phidget_ServoType to PHIDGET_SERVO_RAW_us_MODE to be able to command the Target Position in µs instead of degrees.
Errata: The manufacturer’s data sheet gives 1.75 turns as the operating travel. The actual number of rotations is 7 to 8 as stated in the product specifications below.
