This document discusses winding calculations for three windings - Winding A spanning poles 1-13, Winding B spanning poles 1-11, and Winding C spanning poles 1-10. Each winding forms one pole-phase group. The document also provides an email address for questions.
The document discusses AC motor winding, including definitions of key terms like synchronous speed, phases, poles, active coils, dummy coils, pole-phase groups, coil span, basket and distributed windings, and wye and delta winding connections. It also summarizes common reasons for motor winding failures, such as electrical problems, insulation failure, bearing failure, and various mechanical failures related to the rotor, shaft, or frame of the motor.
This document summarizes a program for calculating three-phase AC winding for single-speed motors. The program includes diagrams for common winding configurations with 12 to 90 slots. It guides the user through entering core dimensions and specifications to calculate the winding configuration, number of turns per coil, wire size and other details. Operating the program is designed to be easy, even for those without experience in computers or motor winding calculations.

Course motor 1-an introduction to electrical motors basicsAli Hassan
This document provides an introduction and overview of electrical motors. It begins by defining electrical motors and their importance. It then discusses the basic principles of how motors work by generating a magnetic field and torque. The document outlines the basic parts of AC motors, including the enclosure, stator, rotor, bearings, conduit box, and eye bolt. It describes open and totally enclosed enclosures. It then provides a detailed table of contents that structures the rest of the document, which will cover motor types, components, theory of operation, and selection procedures.
The document discusses AC servo motors. It covers the principle, characteristics, types, applications and sizing of AC servo motors. Some key points include:
- AC servo motors use permanent magnets and feedback from encoders to provide high torque and precision control.
- Characteristics like speed, torque, frame size, and encoder options can be selected for the application.
- Standard and special motors are used in applications like machine tools, semiconductor equipment, medical devices and more.
- Success stories demonstrate how AC servo motors replaced hydraulic systems and improved textile machines, simulators and other special purpose machines.
- Motor sizing software is available to help customers select the optimized motor for their application.
1. A DC motor runs on direct current electricity. It has a field winding that produces a magnetic field when energized, and an armature winding that rotates when placed in this magnetic field.
2. The key parts of a DC motor include the yoke, poles, field winding, armature core, armature winding, commutator, and brushes. The field winding produces flux, and the rotation of the armature winding within this flux induces voltage that is used to power the load.
3. DC motors can be shunt wound, series wound, or compound wound depending on how the field and armature windings are connected. Shunt and series motors have different torque-speed characteristics due

INSTALLATION NOTICES
1. Electrical Safety
For safety in instalation, ensure that the correct DC voltage is supplied to your cameras
or they will suffer permanent damage.
Don’t plug out when instalation haven’t finished
2. Delivery Safety
3. Accessories
You should use accessories as guest of manufacturer. Ensure that there are enough
accessories in the production package before instalation.
4. Daily remainning
Unplug the power before cleaning. Firstly using wet towel to wash then cleaning again by
dry one.
Using a sponge or nonmetal soft brush to clean lens.
Step 1: Install camera to the decided position
Drill 3 or 4 holes of the installed surface. Use screws for fixing the sole to the wall
surface (amount of screw depend on each bullet camera). If install on the wood surface,
directly screw on the wood surface.
Step 2: Loose the horizontal adjusting ring and adjust the camera to the surveilance
areas, then fix the horizontal adjusting ring back
Camera has two cables: Signal cable and Power cable. Power cable connects to
the 220V Power, switch to 12V for camera running. Signal cable connects to the DVR.
Step 4: After connecting camera with DVR, continuing connect to the Television
or Computer. System connection is in the chart below:
Cameras are fragile so you need attention not to crush or fall down them. Leds or cover
can be brocken or failed

1. An toàn về điện
Khi lắp đặt cần chú ý phù hợp với những thông số nguồn điện cung cấp để đảm bảo
an toàn (thông số nguồn điện được ghi trên tem nhãn của sản phẩm).
Không cắm điện cho camera khi lắp đặt chưa hoàn thiện
2. An toàn khi vận chuyển
Camera là đồ vật dễ vỡ nên khi vận chuyển và lắp đặt cần chú ý không để gây ra các
va chạm, có thể làm hỏng, vỡ ống kính hay mái che.
3. Phụ kiện
Bạn nên sử dụng những phụ kiện theo lời khuyên của nhà sản xuất. Trước khi lắp đặt
nên kiểm tra kỹ đã đầy đủ phụ kiện đi kèm theo hộp chưa.
4. Cách bảo dưỡng hàng ngày
Khi vệ sinh lau chùi sản phẩm, tắt các thiết bị và rút dây nguồn. Sử dụng khăn mềm để
lau. Nếu có nhiều bụi bẩn bám lên thiết bị, lau bằng giẻ ẩm trước sau đó dùng giẻ mềm
lau khô lại 1 lượt. Không sử dụng vật cứng để lau phần ống kính
Bước 1: Lắp đặt camera vào vị trí
Khoan các lỗ vào bề mặt cần lắp theo vị trí của các lỗ ở đáy của chân đế (số lượng tùy thuộc vào từng loại
chân đế). Lấy ốc trong hộp phụ kiện đi kèm để gắn chặt chân đế vào bề mặt tường.
Nếu lắp trực tiếp trên bề mặt gỗ thì không cần khoan mà bắt vít trực tiếp lên bề mặt gỗ luôn.
Bước 2: Sử dụng lục lăng trong phụ kiện đi kèm, xoáy 2 ốc ở 2 bên chân đế và 2 ốc ở phần cuối
của thân camera. Điều chỉnh camera tới vị trí phù hợp với vùng mà màn hình quan sát được rồi vặn
chặt các ốc như ban đầu.
Một camera có 2 đường dây: 1 dây nguồn, 1 dây tín hiệu. Dây nguồn để cắm vào nguồn
220V chuyển thành điện 12V nuôi camera, dây tín hiệu để nối với đầu ghi.
Bước 4: Sau khi kết nối camera với đầu ghi, tiếp tục kết nối với màn hình TV hoặc máy
tính để có thể xem được video trên màn hình. Kết nối hệ thống còn lại theo sơ đồ sau:

1cm
Bước 3: Kết nối dây tín hiệu của camera tới mặt sau của thiết bị đầu ghi hình. Dây tín hiệu được
gắn giắc BNC ở 2 đầu để có thể kết nối camera với cổng video in của đầu ghi. Dưới đây là các bước
