The 25th annual Montana Meat Processors Association Convention and Trade Show was held April 26-29 in Livingston and Big Timber. It included workshop demonstrations, several educational speaker seminars, trade show and a Cured Meat Championship contest. Approximately 35 processing plants from across the state were represented. … Read News
Mechatronics II Laboratory Exercise 7
The stepper motor of Figure 1 does not have a very desirable resolution since it has only one pole pair on the rotor. This formula works for full-step configuration. The half-step configuration doubles the resolution. … Access Content
MICROCONTROLLER BASED SOLAR TRACKING SYSTEM
The inductance L determines the maximum rate of change of the current in the winding according to the formula for an Inductor dI/dt = V/L. Thus when controlled by an L/R drive, the maximum speed of a stepper motor is limited by its inductance since at some speed, the voltage V will be changing … Document Viewer
Industrial Circuits Application Note Microstepping
From the formula above we see that a pulsing torque is developed by the motor (see figure 1a, which also familiar with stepper motor driving and the torque generation principles of a stepper … Retrieve Document
Stepper Motor Drive Circuit
Monostable on time is determined by the formula TON ≈ 0.69 RT CT. To keep the monostable on indefinitely, pull UC3517 can be connected to a stepper motor as a unipo-lar driver. LA, LB, RC and Vss are not used, and may be … Access Document
Brushless Motor Commutation
Also, although it was mentioned that stepper motors are not commutated, it is possible to apply commutation to the stepper motor (i.e. operate as a 50-pole brushless motor), but the pull-out torque curve still applies for maximum torque. … View Full Source
Actuators: Stepper Motors
University-logo Operation of a 2 Phase Stepper motor Improving Resolution Stepper Motor Full Step Resolution In general a stepper motor can have more than 2 phases (recall 3 phase stepper above). In this case we can generalize our formula for full step angular resolution to: Equation for angular resolution … Return Doc

Rotational Speed – Wikipedia, The Free Encyclopedia
For example, a stepper motor might turn exactly one complete revolution each second. Its angular speed is 360 degrees per second (360°/s), or 2π radians per second (2π rad/s), while the rotational speed is 60 rpm. … Read Article

Electric motor – Wikipedia, The Free Encyclopedia
A servo system differs from some stepper motor applications in that the position feedback is continuous while the motor is running; a stepper system relies on the motor not to "miss steps" for short term accuracy, although a stepper system may include a "home" switch or other element to provide long … Read Article
I3 HSC And PWM Tutorial
This output function allows the i³ to be used in motion control applications by operating a stepper motor (through its driver) to a high level of accuracy. The frequency of the PWM output is calculated using the following formula: Frequency = Period – This value (%AQ7-8) sets the period of the output … Access Doc
