Heavy-duty direct current electric motor, JM-DC-FQZ series

The DC motors are designed using advanced technological solutions, ensuring high reliability and efficiency. Their reduced rotational inertia makes them suitable for applications requiring frequent forward and reverse rotations as well as frequent starting and braking.

The motors feature excellent overload performance, with maximum and starting torques significantly exceeding conventional levels. The lightweight design simplifies transportation and installation.

The power ratings comply with international standards for motors used in cranes and metallurgical equipment. The overall dimensions, with one exception, fully conform to international standards, making them easy to integrate into existing systems.

With standardized mounting dimensions, these motors can be adapted to various operating conditions and customized to replace outdated models as needed.

Duty type, protection degree, cooling method, and installation type

1. The motor is designed for continuous duty (S1); other duty types can be recalculated based on the values in Table 1 of the technical data.

Table 1

2. The motor cooling method is independent cooling with forced ventilation, i.e., the motor is equipped with a radial mounted fan, duct ventilation, or an air/water cooler. The relationship between the protection level and the cooling method is shown in Table 2. The required cooling airflow, air pressure, and fan motor power are provided in Table 3. The recirculation fan power for air/no cooler and the cooling water flow rate are listed in Table 4.
