- ⒈Servo motor torque, power, speed, voltage, and current conversion formulas, just remember this is enough
- ⒉Is the speed of the AC servo motor determined by the current or the rotation of the winding?
- ⒊When the servo motor is in position control mode, the calculation formula between the servo motor speed and the input pulse frequency
Conversion between servo motor torque, power, speed, voltage, and current Relationship, you only need to understand the following key formulas:
1. The relationship between torque (T), power (P) and speed (n): T=9550*P/n
2. Calculation formula of power (P): P=T*n/9550 or P=Tπn/30 (in kW)
3. Electrical power (P) and voltage The relationship between (U) and current (I): P=UI or P=Tn/9.55 (when P is in kW, U is in V, and I is in A)
4. Voltage (U ) and torque (T): U=Tn/9.55I
5. Calculation of current (I): I=9.55U/Tn
The torque is also It can be divided into static torque (such as static torque, constant torque, etc.) and dynamic torque (such as vibration torque, transition torque, etc.), which respectively describe the characteristics of the motor in different working states.
By mastering the above formulas, you can effectively calculate and analyze the performance parameters of the servo motor.

The number of revolutions of the motor is related to the number of poles.
The speed formula of AC motor is unified, n=60f/p (1-s)
f: AC frequency, P: Number of motor pole pairs, s: Slip (synchronization when s=0 Machine)
The voltage is the basic guarantee to provide the necessary excitation. As long as it reaches the rating, the value range of s can be determined, and the speed can be determined using the above formula.
The AC servo motor can reach 1 revolution per minute.
The working principle of AC servo motor and how to control the speed:
The rotor inside the servo motor is a permanent magnet. The U/V/W three-phase electricity controlled by the driver forms an electromagnetic field, and the rotor is affected by this magnetic field. Rotate, and at the same time, the encoder of the motor feeds back the signal to the driver. The driver compares the feedback value with the target value to adjust the angle of rotation of the rotor. The accuracy of the servo motor is determined by the accuracy (number of lines) of the encoder.

Servo motor speed formula
Speed (rps) = ( Command pulse frequency * electronic gear ratio) / number of pulses in one revolution of the encoder
If the speed unit is rpm (how many revolutions per minute), then please multiply by 60
Speed (rps) = ( Command pulse frequency * electronic gear ratio) / number of pulses in one revolution of the encoder
If the speed unit is rpm (how many revolutions per minute), then please multiply by 60
