WebMay 5, 2024 · I need to slow my DC motor down considerably, but not limit the torque. Maximum torque for a DC motor is at 0 rpm. The documentation suggests pulse width modulation w/ pulsewidth between .8 and 2.2 ms. Without knowing the PWM frequency, it is difficult to calculate the duty cycle. WebApr 23, 2024 · DC motors speed is generally proportional to applied voltage. (A simple control approach is to use adjustable Buck regulator) However the voltage drop across the winging resistance (and brushes if used) makes the motor slow under load. If the speed is to be maintained across varying load conditions - there are two classical approaches: 1. WebAug 26, 2014 · 1) What to control the motors with. See below! 2) Rheostat or potentiometer.

WebMay 6, 2024 · If you are trying to use slow speed a DC motor is a poor choice without a gearbox to slow things down. The motor has little torque because you are effectively running the motor on low voltage. PWM with a 50% duty cycle is going to behave similar to the motor on 50-60% voltage. WebThe equation for motor speed is: Where: N = motor speed in revs per minute. f = frequency of supply to the motor in Hz. p = number of poles on the stator. s = slip of motor in revs per minute. From this equation, it can be seen that the speed of an induction motor can be controlled in three ways: (a) Change the number of poles.

WebJun 21, 2024 · Oriental Motor manufactures both 2 and 4 pole AC motors. For a 3-phase AC motor with an input voltage of 220VAC, 60 Hz, the motor's synchronous speed (RPM) = 120 x 60 / 4 = 1800 RPM. Synchronous speed is essentially no load speed with the slip. Since applying a rated load would slow down the motor to its rated speed, the difference … WebIn order to maintain torque at a speed other than its rated speed, you need to adjust the frequency in proportion to the voltage. If you want to do it right, you rectify the AC into a DC bus and then use IGBTs to chop up the bus (using PWM) to generate an AC waveform at the frequency and average voltage you need.
