1 |
CM |
(Continuous) Rated voltage |
The input voltage which can satisfy the condition specified by the specification in continuous operation. |
2 |
CM |
(Continuous) Rated output |
The maximum output that can be safely and continuously used under the conditions specified in the specification. |
3 |
CM |
(Continuous) rated torque |
Torque when the rated output is continuously emitted at the rated voltage. |
4 |
CM |
(Continuous) rated RPM |
The rotational speed at which the motor is continuously rated, at the rated voltage. |
5 |
CM |
(Continuous) rated current |
The current when the motor is continuously rated and the rated torque is generated. |
6 |
CM |
Maximum efficiency |
The maximum value of the power consumed by the motor and the ratio of the mechanical output exerted. |
7 |
CM |
No load rotational speed |
Stable revolutions when the rated voltage is added when the load is zero. |
8 |
CM |
No load current |
Even if the external load is zero, there is bearing friction and load by wind loss. So, constant torque is still required to turn at a constant rotational speed, that is the current necessary for that. |
9 |
CM |
Torque parameter |
Since the generated torque is approximately proportional to the current, the Torque ÷ current (Nm/A) is a constant, and this constant is called the torque parameter. |
10 |
CM |
Reverse Voltage parameter |
The Reverse voltage of the motor is proportional to the rotational speed of the motor, and the proportional coefficient to the reverse electromotive voltage parameter. e = Ke x ω (e: Inverse voltage, ω: angular velocity, Ke reverse voltage parameter. ) |
11 |
CM |
Resistance between terminals |
Resistance values measured between coil terminals |
12 |
CM |
Rotor Inertia |
The moment of inertia of the rotor, the higher the value is less responsive |
13
|
CM |
Cogging torque |
The suction force torque caused by the magnetic suction force generated when the rotor is rotated in a non-excited state |
14 |
CM |
Terminal inductance |
Inductance measured between coil terminals |
15 |
CM |
Mechanical time parameter |
Indicates the rise time of the motor startup and the time to reach 63.2% of the rated RPM |
16 |
CM |
Electrical time parameter |
When the motor is fixed so as not to rotate, the time until the current reaches the 63.2% of the saturation current after applying the rated voltage |
17 |
CM |
Motor weight |
Average weight of standard type motors |
18 |
CM |
Maximum temperature of the coil |
The maximum temperature allowed in the coil and the temperature that cannot be exceeded even when the customer uses it |
19 |
CM |
Insulation grade |
It is classified by the heat resistance of the insulating material which is composed, and the E species is 120 ℃. This does not mean that it can operate in 120 ℃ environments, and is expected to be 120 ℃ or less, including temperature rise due to heat generation |
