What is the decisive factor affecting the temperature rise of the motor for the hydraulic pump? Dalan Motor takes you to take a look!

If the temperature rise test value of the special motor for the hydraulic oil pump is too low, it means that the effective material consumption is too high and the manufacturing cost is increased; the test value is too high, and the motor is easy to overheat under normal working conditions. Here, Dalan Motor will talk to you. It is assumed that the design parameters have been optimized to the optimum state, which is the decisive factor affecting the temperature rise of the motor.

Factors that affect the temperature rise during the manufacturing process?:

(1) Winding dipping paint

The dipping paint not only strengthens and solidifies the insulation of the motor, but the impregnating varnish fills the air gap between the turns and the windings to the ground through advanced vacuum pressure dipping equipment.

(2) Matching the stator core with the base

The mating surface of the stator core and the base is an important way to conduct heat of the stator winding and heat loss of the core.

(3) Surface treatment of the base

When the heat loss generated inside the motor is transmitted to the surface of the machine base, it is mainly carried by the fan end through the surface air of the motor.

(4) Motor fan compliance

The fan is the main wind pressure component of the self-fan cooling motor, and its size and shape are the key factors determining the temperature rise level.

(5) Quality control of the film

Core loss is one of the five major losses of the motor. The quality of the punch must be strictly controlled to ensure the stacking factor.

(6) Purity and parameter control of cast aluminum rotor aluminum

For aluminum for cast aluminum rotors, on the one hand, the procurement quality control of aluminum, on the other hand, it has a direct relationship with the aluminum melting process in the aluminum casting process.

(VII) Rotor cast aluminum defect control

The broken bar inspection device is used to check whether the rotor has defects such as thin strips, broken strips, shrinkage holes, shrinkage and pores.
