You must size the short-circuit ground-fault protection device from 150% to 300% of the motor FLC … At this point, I’ve covered most of the typical robotics uses for rotating motion and how to properly design the systems electrically to meet the basic mechanical demands of a project. However, its battery capacity calculator assumes that you have a coefficient of friction of one and that the motor is basically operating at full load 100% of the time so it vastly overestimates capacity. The number one calculation to make when sizing a motor for a rotary application is the calculation of the load inertia. For example, if you want to use a CIM motor to lift a 1kg mass at an extension of 0.5 meters: With these results, we know with a gear ratio of 3:1 the CIM can easily supply the torque needed at over nine times the required minimum speed! xref

We can use a higher ratio and still move plenty fast and raise the lifting capability as needed. Motor Wire Size Calculator 0000010058 00000 n
These Online Motor Sizing Tools are designed to make sizing a motor faster and easier. You can also take some shortcuts by assuming you want to operate a bit below max rpm for a given motor and ensure it has enough torque to accelerate your robot at a semi-reasonable pace at startup. The other motor(s) in the group (phase) is the 10-hp 3-phase motor, as indicated by the shaded area. We will assume we are just starting to move so rpm = 0 and torque = 2.41 N*m. If we have two driven wheels we can double this force and determine the acceleration from stall. The force/acceleration calculation from the previous section can be reused by making friction = 1 for positive engagement. Dimensions and mass (or density) of load 2. This is determined by the weight of the bot, how much of that is on a driven wheel, the wheel diameter, and the coefficient of friction between the floor and wheel. 0000057443 00000 n
If you are always moving an offset mass that doesn’t change much, having a counterweight that counterbalances the torque from the load can drastically reduce the load on your joint. There, you can find a great article about optimizing the gearing for a robot drivetrain and a combat robot drivetrain calculator that makes it easy to determine what wheel diameter and gearing is required. Now let’s begin with the steps towards sizing your servo motor. The Drive Motor Sizing Tool is intended to give an idea of the type of drive motor required for your specific robot by taking known values and calculating values required when searching for a motor.

The typical two-a-day segments are: 6 hour cycles, 8 hour cycles, and 10 hour cycles. Motor Sizing Calculations This section describes certain items that must be calculated to find the optimum motor for a particular application. With that information in mind, let’s dive into the actual calculations and assumptions used for making motor design decisions with real-life examples. Let’s say we have a 4-inch diameter wheel we want spinning at 600RPM with the CIM motor. Motor sizing calculations Torque speed curves can be calculated for any motor using these electrical and thermal limits. Keep in mind that if you are lifting a proportionally lighter load, the motor will be able to turn proportionally faster. 0000016112 00000 n

Let’s we calculate required cable sizing for 5.5kW/7.5HP motor which is operated at 415V, 0.86pf. Which do you use — full-load current (FLC) or full-load amperes (FLA) — for your motor calculations? When designing your bot, you need to know the ballpark for how much it will weigh and what top speed you want, and if it needs to carry any extra weight lump that in as the robot weight. Selection procedures and examples are given. Motor Displacement (in 3 per rev) Motor RPM; GPM Flow Required; Example: How many GPM are needed to drive a 3.75 cubic inch motor at 1500 rpm? The shaft power - the power required transferred from the motor to the shaft of the pump - depends on the efficiency of the pump and can be calculated as Ps (kW) = Ph (kW) / η (3) Cable length = 200 m. Load Current = P / (1.732 x V x Pf x Eff) —> (P = √3 x Vx I CosΦ = for three phase circuits) = 125000 / (1.732 x 415 x 0.8 x 0.94) ~ 230 A. The speed of your bot is the wheel circumference2rtimes the rpm, with unit conversions where needed. For example, if you want to move a mass of 1kg at the end of a 0.5m arm, then you only need 0.5kg*m of torque or 4.9Nm minimum (gravity applying a force of 9.8N/kg). Fig. 0000056623 00000 n
