On / off operation in a sequence
During operation, the winding current is applied to the corresponding coil of the pulse motor 2
The pulse motor 2 rotates sequentially, and the pulse motor 2 rotates. As described above, the step angle of the motor 2 is
1.8 ゜, in other words, the motor 2 runs every minute without a speed reducer
It rotates at a low speed of 98 rotations. Also, the oscillation frequency

The relationship with the motor speed will be described. As can be seen from the sequence of FIG.
In the case of phase excitation, the frequency of the divided output and the clock frequency
(Frequency for rotating the motor by 1.8 °) is 4.
And the number of revolutions per minute N (RPM) of the motor
The number of rotation steps is ns (200 at a step angle of 1.8 °),
Number of division stages is 2ⁿ(2 to the power of n), oscillation frequency is f (Hz)
Then, it can be calculated from the following equation. N = (f × 4 × 60) / (2ⁿ× ns) (RPM) Here, 60 is used to convert the number of revolutions per second to the number of revolutions per minute.
Is the coefficient of The number of dividing stages is 15 and the oscillation frequency is
The motor rotation speed N at 2.676 MHz is 2ⁿ= 2
^Fifteen= 32768 and f = 2676000 Hz
N = (2676000 × 4 × 60) / (32768)
× 200), which is approximately 98 (RPM). Also,
When the oscillation frequency is 2.730 MHz, N = (273
0000 × 4 × 60) / (32768 × 200)

Driving at the above low frequency of about 82 Hz corresponding to several areas
Even if it moves, the motor vibration can be sufficiently suppressed. As described above, the operation of driving the motor at a low frequency is described.
As a result, heat generation of the motor is mainly caused by copper loss due to coil resistance.
And the consequences of iron loss are virtually negligible,
Reduced. Note that, as described above, the pulse motor 2
When the data core RC is composed of massive pure iron,
The motor vibration is further suppressed by the generated eddy current. Soshi
Therefore, a high-efficiency pulse motor 2 was used as the firing motor.
As a result, a small motor can be used without using a reducer.
The required output torque can be obtained.
With a length of 55 mm, a torque of 1.5 kgcm is obtained.
Synchronous motor with an outer diameter of 60 mm and a total length of 60 mm
Is superior to the output torque of about 500 g-cm. When the pulse motor 2 rotates, the motor
