Nippon Gear Co.
Nippon Gear DC Motor

Manufacturer: Nippon Gear Co., Ltd.
Features
- High starting torque characteristics appropriate for valve characteristics
- Motors to which the line starting method is applicable
Because the motors to which the line starting method is applicable do not require current-limiting resistance at the time of starting nor a switching circuit, which are required for general-purpose DC motors, the circuit can be simplified.

Explanation on symbols
R/C: Reversible electromagnetic switch
51H: Thermal relay heater
R: Discharge resistance
(Note 1) External wiring to E2 terminal is prohibited.
(Note 2) R represents discharge resistance.
(Note 3) When the motor size is #7.5 and larger (with interpole), B2 is used instead of A2 as the terminal marking.
