1. Locked-rotor torque, locked-rotor torque classification continuous locked-rotor torque and peak locked-rotor torque, continuous locked-rotor torque is defined as the dc torque motor (direct-drive motor) in a blocked state its stable temperature rise shall not exceed the allowable values, and can work for a long time, the condition of continuous locked-rotor torque, torque is called expressed as Mn, unit for N.m.
The peak plugging torque is defined as the maximum current of dc torque motor (direct drive motor) due to the maximum current of permanent magnet material.
The influence of magnetic steel performance.
Some products use high performance magnetic steel, the torque is only limited by the maximum temperature rise, the peak torque is greatly improved.
This is Mf, the unit is N.m.
: 2. Locked-rotor voltage blocking voltage and peak voltage can be divided into continuous wall turns locked-rotor voltage, voltage is defined as a continuous locked-rotor dc torque motor (direct-drive motor) to produce continuous locked-rotor torque exerted on both ends of the motor voltage, expressed as the Un, unit V.
The peak plugging voltage is defined as the voltage applied at both ends of the motor when the dc torque motor (direct drive motor) produces a peak blocking torque. It is expressed as Uf and the unit is V.
3, locked-rotor current: locked-rotor current is divided into continuous locked-rotor locked-rotor and peak current, locked-rotor electric current is defined as A consecutive dc torque motor (direct-drive motor) to produce continuous locked-rotor torque when the armature current, expressed as the In, the unit is A.
The peak plugging current is defined as the dc torque motor (direct drive motor), and the armature current of the peak blocking torque is expressed as If, the unit is A.
4. Continuous traffic control power: the control power of the dc torque motor (straight drive motor) generates a continuous stop torque, which is expressed as Pn, and the unit is W.
5. Peak plugging control power: the control power of the dc torque motor (direct drive motor) produces peak blocking torque, which is denoted as Pf, and the unit is W.
6. Maximum no-load speed: the dc torque motor (direct drive motor) is applied to the peak plugging voltage, which does not connect the load speed when the load is connected;
The unit is r/min or RPM.
7. Anti-electric potential coefficient: the anti-electric potential coefficient is the generation voltage value of the motor at 1r/min that is measured in the state of the generator when the torque motor is dragged. The unit is V/r · min - 1.
8. Torque sensitivity: the ratio of the peak blocking torque of the dc torque motor (direct drive motor) to the peak plugging current, i.e., the torque generated by each ampere current is expressed as Kt, and the unit is N.m/A.
Dc torque motor, torque ripple coefficient: pros and cons to () a direct-drive motor rotor rotating each week, locked-rotor torque output of the difference between the maximum and the minimum and maximum and minimum value, the ratio of the sum, represented by %.
The rotation direction of the dc torque motor (direct drive motor) is defined as: from the load side, the motor will rotate clockwise in clockwise direction and turn counterclockwise to reverse.
11, electrical time constant: motor circuit electromagnetic inertial delay time, the dc torque motor (direct-drive motor) electrical time constant is defined as the armature inductance and the ratio of the armature resistance, expressed as Τ e, unit for ms.
