Brief Introduction

 

The working principle of ZDB DC emergency oil pump 75 kw motor is mainly based on the operating mechanism of DC motor. When DC current flows into the commutator through the brush and is then transmitted to the rotor coil, the rotor coil generates a rotating magnetic field under the action of the stator magnetic field.

 

The rotating magnetic field of the rotor of 75 kw motor interacts with the fixed magnetic field of the stator to form torque, which drives the rotor to rotate. The rotation of the rotor drives the impeller or piston of the oil pump to work, realizing the suction and delivery of hydraulic oil. The working pressure and flow of the oil pump can be controlled by adjusting the current and voltage.

 

Characteristics of DC motors

 

1. Excellent speed regulation performance Smooth speed regulation can be achieved by adjusting the armature voltage or magnetic field current, and the response speed is fast, which is suitable for precision control scenarios (such as electric vehicles and industrial equipment).

2. Large starting torque It can provide high torque at start-up, which is suitable for heavy-duty start-up (such as cranes and winches).

3. Complex structure and high maintenance requirements It includes wearing parts such as brushes and commutators, which require regular maintenance, but modern brushless DC motors (BLDC) have a simpler structure.

4. Reversibility It can be operated as an electric motor or generator, and the energy conversion is flexible (such as a regenerative braking system).

5. Efficiency and loss Brushed motors are less efficient due to brush friction and resistance loss, while brushless motors are more efficient.
