Pololu micro engines HP - High Power

The Pololu micro motors High Power – which will come in handy

The motors are Pololu is a popular product among students of technical universities. Are an excellent basis for building different robots. The equipment is characterized by very high strength and strict compliance with the stated manufacturer parameters. Because of this, these parts can check with several different projects without the need to purchase the following parts. Series High Power is characterized by greater opportunities than those that offer a series of Medium Power and Low Power means that the engines offer a greater number of rotations, the higher the torque and the gear ratio is better. This means that they are "stronger" (e.g., be able to lift more weight) and faster. Suitable, for example, when large constructions or robots in such projects, which will require increasing the efficiency of the device. The mobile robot is able to move large weights (e.g., model MDP-a) or to achieve greater speed (for example, model racing car). The manipulator will be able to move faster and swim great hardships. However it should be noted that such advantages are also associated with greater energy demand for the engine. This means that the device, which will be equipped in this kind of engine, you will need more batteries (especially larger capacity). Of course, such decisions depend on the individual principles of each project.

What we offer in this category

In our offer you will find equipment is supplied with the voltage from 3 V to 9 V. the Engines consume different amounts of electricity depending on the current load, as well as whether they are already in motion. More light need to be under a heavy load and at start-up, and the lowest values will be required during constant motion with the highest peak. Each commodity has a detailed description that distinguish individual cases. For example, motor, gearbox 30:1 and a torque of 0.6 kg*cm no load will be able to reach 1000 rpm, using a 120 mA, with a stationary shaft, and have to use 1600 mA. We have motors which with no load will consume about values, about 70 mA, 80 mA and 120 mA. Reducer is a crucial parameter of this type of device. You can't determine which option is better or worse – this distinction can only be applied for specific projects. Gear depends, what speed can reach the motor shaft and which will prevail. On one bowl of scales - the torque (force), and on the other the speed of rotation – speaking one, adds a second. We have the motors on the gearboxes 5:1, 10:1, 15:1, 30:1, 50:1, 75:1, 100:1, 150:1, 210:1, 250:1, 298:1 and even 1000:1. Engine parameters depends on the final torque. For example, on the basis of information that the engine torque is 1.6 kg*cm, it can be concluded that the limit value of the power that this engine, przyrównywana weight of 1.6 kg, is suspended at a distance of one centimeter from the axis of the shaft so the engine can continue to operate. Put more weight or increasing the distance from motor shaft will make it impossible to work. In offer we have devices in which the torque values in the range of from 0.1 kgf*cm, 0.22 kg*cm, 0.3 kg*cm, 0.6 kg*cm, 1.1 kg*cm, 1.6 kg*cm, 2.2 kg*cm, 2.9 kg*cm, 3.4 kg. cm, 3.6 kg*cm, 4.3 kg*cm 5 kg*cm and even 9 kg*cm of the Declared maximum speed of the products (at no load): 32 rpm 100 rpm 120 rpm 140 rpm, 200 rpm, 320 rpm, 400 rpm, 630 rpm, 1000 rpm, 2000 rpm, 3000 rpm, 6000 rpm. These engines always are perhaps the smallest elements – the diameter of each of them is the inclined plane 12 mm, weighs 10 g, depending on model length is 24 mm, 26 mm or 30 mm and the shaft diameters 3 mm or 4.5 mm. Part of them has specifically placed a second shaft on the opposite end of the engine – it has the objective to provide a framework for the inclusion of the sensor. This will allow current measurements of the speed of rotation of the motor shaft. Using, for example, the magnetic sensor is in this place (by putting a magnet on the end of the middle finger measurement), for example, you can implement speed control of the motor PID (this will also have a bridge H – also available from Pololu).
