Tongmao linear motor platform common parameters are as follows:
    1. The maximum voltage (max. voltage ph-ph) - the maximum power line voltage, mainly related to the ability of the motor insulation;
    2. Peak Force - The peak thrust of the motor, in seconds and seconds, depends on the safety limit capability of the electromagnetic structure of the motor;
    3. Peak current - Maximum operating current, corresponding to the maximum thrust direction, lower than the demagnetization current of the motor;
    4.Maximum Continuous Power Loss (Max. Continuous Power Loss)—determine the temperature rise condition and heat dissipation conditions, the motor can be continuously running the upper limit of heat loss, reflecting the thermal design level of the motor;
    5.Maximum speed (Maximum speed) - The maximum operating speed in determining the power supply line voltage, depending on the number of back-EMF lines of the motor, reflecting the results of the electromagnetic design of the motor;
    6. Motor Force Constant (motor force constant), the motor's thrust current ratio, unit N / A or KN / A, reflecting the results of the electromagnetic design of the motor, in a sense, can also reflect the level of electromagnetic design;
    7. Back EMF (Back EMF) - motor back EMF (coefficient), unit Vs/m, reflecting the results of the electromagnetic design of the motor, affecting the maximum operating speed of the motor under the determined supply voltage;
    8. Motor Constant (Motor Constant) - the ratio of the square root of the motor thrust and power consumption, unit N / √ W, is a comprehensive manifestation of the motor electromagnetic design and thermal design level;
    9. Magnetic pole pitch NN (Magnet Pitch) - the magnetic pole spacing distance of the motor secondary permanent magnet, basically does not reflect the motor design level, the driver needs to be based on the resolution of the feedback system to solve the motor electrical angle required for vector control;
    10. Resistance per phase - The phase resistance of the motor, given below is often the line resistance, Ph-Ph, and the motor heat has a greater relationship, in the sense of reflecting the level of electromagnetic design;
    11. Inductance per phase (Induction per phase) - The motor's phase inductance, given below is often the line inductance, Ph-Ph, and the motor back EMF has a relationship, in the sense can reflect the level of electromagnetic design;
    12. Electrical time constant (Electrical time constant) - the ratio of the motor inductance and resistance, L / R;
    13. Thermal Resistance - This is related to the heat dissipation capability of the motor and reflects the thermal design level of the motor.
    14.Motor Attraction Force—Plate type core structure motor, especially permanent magnet type motor, the normal attractive force of the secondary permanent magnet to the primary core is higher than the rated thrust of the motor by an order of magnitude, and the motor is directly decided to use. The bearing capacity and selection of the support rail of the linear motion axis.
    Linear motor platform selection thrust speed, and then see the continuous power consumption, thermal resistance and cooling methods and conditions, etc., look again at the supply voltage and current, the requirements for rapidity also depends on the electrical time constant. Personal opinions, reflecting the performance level of the linear motor platform are the thrust stability, motor constants and thermal resistance, but the thrust stability index may not be directly given by most manufacturers.
The thrust coefficient of the motor is marked by the output current ratio, such as N/A, Nm/A
The back electromotive force coefficient is indicated by the voltage speed ratio, such as V/(m/s), V/(rpm), etc.
  The electromechanical conversion formula of the motor can be used to derive the relationship between them. The specific process is as follows:
    The mechanical output power of the linear motor platform is Pm = F * v = Cm * I * v, where Cm is the thrust coefficient, I is the current, v is the motor speed;
    The electromagnetic conversion power in the electric power consumption of the linear motor platform is: Pe=ε*I=Ce*v*I, where Ce is the back electromotive force coefficient, v is the motor running speed, and I is the current;
    Let Pm = Pe, then there Cm * I * v = Ce * v * I, which can be derived Cm = Ce, which can be marked 1, ε is regarded as the back-EMF of the DC system;
    Consider Pe=3ε*I, ie, ε is the opposite potential, then it can be marked as 3;
    Consider Pe=sqrt(3)*ε*I, that is, ε is the back electromotive force, which can be labeled as sqrt(3), ie, 1.732;
    Given that ε is an amplitude rather than a valid value, then in addition to sqrt(2), there are 1.732/1.414=1.225.
