• Low Cost Automation Tutorial: Stepper Motors
by the following equations. Example. Case for: Step angle：0.72 deg., Pulse rate: 100Hz... 12（r／min）・・・ 12 rotations per minute. Case for: Step angle：0.72 deg., Pulse rate: 1000Hz... 120（r／min）・・・ 120 revolutions per minute. (4) About "Origin position" (home position). Since the stepper motors do not have own
• Motor Calculations
by the rotational distance per unit time. Prot = M x ω. Where: Prot = rotational mechanical power. M = torque. ω = angular velocity. The most commonly used unit for angular velocity is rev/min (RPM). In calculating rotational power, it is necessary to convert the velocity to units of rad/sec
• Motor sizing made simple
for the same amount of time it has been on. Motors with less than 100% duty cycle also have a maximum run-time limit such as 30 min. A 50% duty cycle motor with a 30 min run time

with electro-magnetic brake. Often used for Z axis control since the load does not fall since the "power-off" brake can retain the shaft during a power outage. Overrun: 0.5~1 revolutions. Rating: Minutes. Simple velocity control. Variable speed motor. Overrun: 0.5~1 revolutions. 90〜1400r／min（50Hz
• Software Review: FEA for Electric Motors
about half a day to create an FEA model. The motorsimulation software lets users build a model in about 20 min. The 2D version of the package works well for motor design. The software exploits the symmetry of a rotary motor to create a representative segment of a design and speed processing time
