Vibration Frequency Calculator. This calculator can be used to either calculate the vibration frequency of an ERM from the motor speed, or the motor speed from the desired vibration frequency. Simply enter your new speed in RPM or frequency in Hz, if you have a specific motor in mind then both these values can be found on the datasheet.
Mt = e x Pv. where: Pv = Pc + Po. with Pv = total weight of the vibrating complex (Kg); Pc = weight of the elastically isolated appliance (Kg); Po = weight of the installed electric vibrator (or vibrators) (Kg); hypothetic weight to be subsequently compared to that of the determined vibrator.

VIBRATING SCREEN CAPACITY CALCULATIONS Throughput per square foot of screen area is the name of the screen game, and no design engineer wants to be considered short in the area of capacity and efficiency. It behooves the buyer/operator to examine and evaluate the data available before committing to any screen type or system.
to choose a vibrator as indicated in the guide. Other Important Factors to consider when selecting vibrators: • If your stored material is best categorized as coarse, you may achieve the best results using a Linear Vibrator (pneumatic piston) or a higher force Rotary Vibrator (motor-driven hydraulic, pneumatic or

Figure 7: This screen shot from a power analyzer shows how the delta measurement function can be used to derive true readings, and phase power, even when the phases are unbalanced. Some power analyzers have a motor option in which the speed and torque signals can be integrated in this manner.
Figure is multiplied by the sq. footage of the screen deck. • Calculation gives the basic capacity of each deck and the total capacity of the vibrating screen. • The vibrating screen capacity is determined: • Using a standard sizing formula (9 variables). • Basic capacity of each deck opening. • Unique factors of that application. •
May 24, 2009· Power required to generate α angular acceleration can be found from the following equation. P= I.α. Now Total Power required for our application is. P = I.α + 2.π.N.T/60. Now we can select a motor which can deliver power we calculated. Note:-While calculating torque you should also consider all the friction couples in your application.
Determining Motor Loads Input Power Measurements When “direct-read” power measurements are available, use them to estimate motor part-load. With measured parameters taken from hand-held instruments, you can use Equation 1 to calculate the three-phase input power to the loaded motor.
Electrical motor loads are calculated from power in kW and full rated load in kW.Following is the formula how to calculate Motor loads. Example : We have 1 unit Induction Motor with 30 horsepower (hp),running with 34.9 amps for amperage load and 460 volts 3 phase and power factor value is 0.75 and motor efficiency is 85%
Calculate the weight of the material in the transition or sloping part of the bin. Normally this is the only place where Rule of Thumb: for self-cleaning screen use a vibrator with a centrifugal force (impact) four (4) times the weight of sound than an electric motor.The life expectancy is 2-3 times

Conversely, if the motor is rated at 1.5V using a 3V battery runs the risk of immediate damage the motor (as would anything above the Maximum Operating Voltage). The reduced voltage causes motors to turn slower. This reduces the torque handling capabilities for DC and gearmotors, whilst causing vibration motors to vibrate less.
Construct a table of the motor mechanical power at various points from no-load to stall torque. Since mechanical power output is simply the product of torque and speed with a correction factor for units (see section on calculating initial power requirements), power can be calculated using the previously plotted line for speed vs. torque.
The rated output (P) is the mech anical power that a motor can output. The rated torque (T) and the rated speed (N) are related to the rated power as follows: P=0.105×T×N Electrical Time Constant The transient response time to the current that flows to the armature of a motor to which a power supply voltage is applied.
Disconnect the power supply to the vibrator to prevent unintended or unexpected starting of the vibrator while adjusting the weights. Using the appropriated sized wrench, remove the four bolts that hold the vibrator’s weight cover in place. Repeat on the opposite end of the vibrator. Once the cover is removed the weights can be adjusted.
