How is the number of motor encoder lines calculated?

The number of motor encoder lines refers to the number of pulses output by the encoder, which is usually used to measure the speed and position of the motor. The number of wires is calculated based on the resolution of the encoder and the number of poles of the motor.

The resolution of an encoder refers to the number of pulses output per revolution, which is usually expressed as a pulse per revolution (PPR). For example, a 1000ppr encoder outputs 1000 pulses per revolution.

The number of poles of the motor refers to the number of poles that the motor passes through in one revolution. For example, a 4-pole motor passes through 4 poles per revolution.

Based on the resolution of the encoder and the number of poles of the motor, the number of lines of the motor encoder can be calculated. It is calculated as follows:

Number of lines = encoder resolution Number of poles of the motor.

For example, a 1000ppr encoder and a 4-pole motor calculate the number of wires as:

Number of lines = 1000 4 = 4000

Therefore, the number of wires of this motor encoder is 4000.

It should be noted that the higher the number of encoder lines, the higher the measurement accuracy, but at the same time, it will also increase the complexity and cost of the system. Therefore, when choosing a motor encoder, it is necessary to consider the actual needs and costs.

The number of encoder lines is to divide the motor rotor into 2048 equal parts, the A B pulse is used to measure the rotor speed and steering, and the Z pulse is the relative zero position of the rotor.

This encoder signal line has k1, k2, k0 and are two groups, can you explain what signal this is? In addition, some motors require a rotary encoder on the bearing end.

Can you explain it, thank you.

This number of lines is the resolution of the encoder, that is, the number of pulses emitted by one revolution, the encoder does not have frequency doubling technology, it is the frequency doubling technology realized by the phase difference relationship of the encoder output pulse (A and B phase) when the receiver processes the pulse and the pulse is destroyed.

For example, if the encoder has 1000 lines, then the resolution of the encoder is 1000. Regardless of the unit, the ultimate thing to know is how many pulses the encoder outputs in one turn. The common encoder output signal has ABZ three-phase, in which AB phase is the pulse output signal, Z phase is the number of turns, AB two phases are 90° apart, and the rotation direction is judged according to whether A is ahead of B or lags behind B.

Encoder photoelectric code disc of a week of engraving, incremental disc engraving line can be 10 lines, 100 lines, 2500 lines of engraving, as long as the disc can be engraved, the encoder can distinguish the angle, for general calculation, to 360 degrees of marking the number of lines.
