- 2024-08-28Detailed explanation of motor winding classification
1. Single-layer windings Definition: A winding with only one effective coil side embedded in each stator slot, and the total number of coils is half of the total number of slots in the motor. Advantages: a. The winding has fewer coils and ...
- 2024-08-26Ways to reduce motor losses and improve efficiency
Since the loss distribution of the motor varies with the power size and the number of poles, in order to reduce the loss, we should focus on taking measures for the main loss components of different powers and pole numbers. Some ways to red ...
- 2024-08-23How much axial preload should be added to the motor bearing?
When discussing axial preload for motor bearings, there are several key factors to consider: the operating conditions of the motor, the type of load (static or dynamic), ambient temperature changes, and expected service life. Load type: For ...
- 2024-08-22Motor export process standards and procedures
The export process and procedures of motors are regulations that motor exporters must understand and comply with. This article will introduce the export process and procedures of motors in detail, including export declaration, inspection and ...
- 2024-08-21What are the measures to control the temperature rise of the
The temperature rise of the motor stator winding is positively correlated with the current. When the current increases, the temperature rise will naturally increase, and the increase will be greater. In addition to the influence of current, ...
- 2024-08-20What factors should be considered when choosing bearing fits
The most widely used bearing in motor products is rolling bearing. Rolling bearing is a standardized component with advantages such as low friction, easy starting and simple replacement. When we are engaged in daily maintenance or mechanical ...
- 2024-08-19Characteristics and Cause Analysis of Motor Overload Fault
Motor overload refers to the state where the actual operating power of the motor exceeds the rated power. When the motor is overloaded, the motor will heat up severely, the speed will drop, and it may even stop; the motor will make a low muf ...
- 2024-08-16YBBP Motor Introduction
The YBBP motor is a type of explosion-proof electric motor specifically designed for use in hazardous environments such as mines and petrochemical facilities. It is engineered to meet stringent safety standards for explosive atmospheres. Her ...
- 2024-08-15What performance of the motor is affected by winding slot ma
A motor factory has manufactured nearly 100 YKK high-voltage motors for customers, with frame sizes ranging from H450 to 710. The heat load was designed to be very low, and the design temperature rise was lower than 68K. However, within less ...
- 2024-08-14Characteristics of variable frequency motor
B-class temperature rise design, F-class insulation manufacturing. The use of polymer insulation materials and vacuum pressure varnishing manufacturing process and special insulation structure greatly improves the insulation withstand voltag ...
