Rated voltage[ V ]
A voltage that is required to run a motor at the rated load and rated speed. (A voltage when applied to between DC motor terminals.) The rated voltage to use mustbe ±10% of the marked voltage. (Please contact us for use outside this range.)

 No-load speed[ min-1 ]
Speed per minute when a motor is run at the rated voltage under no load.

 No-load current[ mA ]
A value of current when a motor is run at the rated voltage under no load.

 Starting torque[ mNm ]
Maximum current that flows at the rated voltage when a DC motor is started or locked.

 Starting current[ mA ]
Maximum current that flows when the rated voltage is applied.


 Output[ W ]
The DC motor output can be calculated by the following equation:


 Maximum efficiency[ % ]
The maximum value of the input-to-output ratio.

 Terminal resistance[ O ]
Resistance between winding/brush and commutator/terminal or lead wire. A value of resistance measured between terminals of a DC motor. In the case of the graphite brush, the resistance changes according to current.

 Rotor moment of inertia[ gcm2 ]
Moment of inertia of the mass of the rotor.

 Rotor inductance[ mH ]
An approximate value measured between terminals of a DC motor with a measuring frequency of 1 kHz.

♦ Mechanical time constant[ ms ]
A constant (tm) that indicates a time required by the DC motor from rising from the rest state to reaching 63.2% of the no-load Speed.

♦ Torque constant[ mNm/A ]
Torque that occurs when current is 1A.

♦ Winding allowable temperature[°C]
Winding employed is insulating heat-resistant type B (130°C).
If you need special heat resistance, please contact us.
