Stepper Motor Calculator
Read full descriptionHide full description
The Stepper Motor Calculator is designed to calculate the maximum speed of a stepper motor, as well as the minimum time per step and the maximum power dissipation. A stepper motor, also known as a step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed. Stepper motors are often computer-controlled and can be categorized under motion-control positioning. In this application, the stepper motor is part of an open-loop system for holding or positioning objects. The stepper motor is a popular type of synchronous motor because it allows for precise movements or "steps." This type of motor also produces a lot of torque given its size and is mostly used in industrial applications. Because they allow very small movements, stepper motors are also found in the field of lasers and optics, where precision positioning is often required. These motors are often part of linear actuators, goniometers, and rotation stages. Similarly, stepper motors are used in fluid control systems, particularly in positioning valve pilot stages. They can also be found in packaging machinery. Stepper motors are mostly used in 3D printers and CNC machines as actuators. They are also used in disk drives, printers, slot machines, camera lenses, and image scanners. To compute the maximum revolutions per second, divide seconds per step by steps per revolution. Rev/sec = V/(L*2*Imax)/(steps/rev) Pmax = 2*Imax*V Where: V = Voltage - Volts (V) L = Inductance - milliHenry (mH) Imax = Current - Amps (A) Pmax = Max Power - Watts Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.

Verdict
The clearest difference is price: Controller Diagnostics at Free against Stepper Motor Calculator's $2.99. Controller Diagnostics also leads on update cadence (every 3 weeks vs every 32 months). Stepper Motor Calculator's advantage is iOS requirement (13 vs 16.0). On ads, in-app purchases and device support there is nothing between them.
