Pololu item #: 1058
Brand: Power HD
Status: Discontinued at Pololu 
RoHS 3 compliant


The 3001HB is a great, general-purpose, low-cost standard analog servo from Power HD. Two ball bearings help reduce friction and improve performance. This is one of our most popular standard-size servos. Servo horns and associated hardware are included.

The servo cable is terminated with a Futaba-compatible JR-style connector.




Overview

The HD-3001HB is a great general-purpose, standard-size servo. Two ball bearings help reduce friction and improve performance. The lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. You can find more information about this servo under the specifications tab and in its datasheet (379k pdf).

The picture below shows an example of the hardware that might be included with this servo (hardware might vary):

This servo is also compatible with our Mounting Bracket for Standard-Size Servos:

If you are looking for a similar servo that is capable of continuous rotation speed control as opposed to limited-range position control , consider the Power HD continuous rotation servo AR-3606HB, which has comparable size, weight, speed, and torque.

Note that, as with most hobby servos, stalling or back-driving this servo can damage it.

Comparison to the FEETECH FS5103B servo

The FEETECH FS5103B servo is a lower-cost alternative to the 3001HB with nearly identical dimensions and similar performance. The two servos should be generally interchangeable for most applications. The picture below shows both the FS5103B and the 3001HB side by side:

Frequently-asked questions

What are the wires coming out of my servo?

Most standard radio control (RC) servos have three wires, each a different color. Usually, they are either black, red, and white, or they are brown, red, and orange/yellow:

  • brown or black = ground (GND, battery negative terminal)
  • red = servo power (Vservo, battery positive terminal)
  • orange, yellow, white, or blue = servo control signal line

Please check the specs for your servo to determine the proper power supply voltage, and please take care to plug the servo into your device in the proper orientation (plugging it in backwards could break the servo or your device).

Note: Some of the servos we carry also have an optional fourth green wire that is separate from the three standard ones. This wire provides access to the feedback potentiometer, allowing you to directly measure the position of the output. The servos with this extra wire have "with Position Feedback" at the ends of their product names. The picture below is an example of such a servo.

How many degrees can this servo turn? Why do you not list it with the other specifications?

We do not specify the range of rotation of our servos because this information is not generally available from servo manufacturers. RC servos are usually intended for controlling things like the steering mechanism in an RC car or the flaps on an RC plane. Manufacturers make sure that the range is enough for these typical applications, but they do not guarantee performance over a wider range.

This means most RC servos will rotate about 90° using the standard 1–2 ms pulse range used by most RC receivers. However, if you are using a controller capable of sending a wider range of pulses, many servos can rotate through almost 180°.

You can find a servo’s limits if you use a servo controller that can send pulses outside of the standard range (such as our Maestro servo controllers). To find the limits, use the lowest possible supply voltage at which the servo moves, and gradually increase or decrease the pulse width until the servo does not move any further or you hear the servo straining. Once the limit is reached, immediately move away from it to avoid damaging the servo, and configure your controller to never go past the limit.

You might be wondering why we do not just follow the above steps for all the servos we carry and list a specification for degrees of rotation. Unfortunately, since servo manufacturers do not specify the range of rotation, it might change from one manufacturing run to the next. They will not inform us about changes that are not specified, and we have no way of knowing if or when they might change their manufacturing process.
