What is the difference between ZDY1 21 4 motor and ZDY1 21 4B motor?

The difference between the two is that their power is completely different, and in addition, they have been optimized for many functions, and the use effect is relatively better.

It is composed of four subsections, including the motor type code, the motor characteristic code, the design serial number and the excitation mode code.

1. The type code is the Chinese pinyin alphabet used to characterize the various types of motors.

For example: asynchronous motor y synchronous motor t

Synchronous generator TF DC motor z

DC generator ZF

2. The characteristic code is to characterize the performance, structure or use of the motor, and it is also expressed by Chinese pinyin letters.

For example, the flameproof type is represented by B and the axial flow fan is YT

Electromagnetic brake type YJ frequency conversion speed regulation type YVP

Pole multi-speed YD crane with YZD, etc.

3. The design serial number refers to the order of motor product design, which is represented by Arabic numerals. For the first design of the product is not marked with the design serial number, the series of products derived from the product according to the design order.

For example: y2 yb2

4. The excitation mode code is represented by letters, S represents the third harmonic, J represents the thyristor, and X represents the phase complex excitation.

For example: y2-- 160 m1 8

y: model, representing asynchronous motor;

2: design serial number, "2" indicates the product with improved design on the basis of the first time;

160: center height, is the height from the center of the shaft to the plane of the base;

M1: Frame length specification, M is medium, where footnote "2" is the second specification of M-type core, and "2" type is longer than "1" type core.

8: Number of poles, "8" refers to 8-pole motor.

For example: y 630-10 1180

y represents an asynchronous motor;

630 means power 630kw;

10 poles, stator core outer diameter 1180mm.

ZD and ZDY series conical rotor three-phase asynchronous motors are closed, self-fan-cooled, cage motors with braking devices, and are special motors supporting electric hoists.

The differences between them are:

ZD series motors are suitable for electric hoist lifting or mechanical devices that require large braking torque;

ZDY series motors are suitable for electric hoist operation or mechanical devices that require a small braking torque.

The ZD series motor has a large flange on the transmission end cover, and the ZDY series motor has a small flange, and the shaft extension is connected by rectangular spline.

ZD is the code name for a conical rotor three-phase asynchronous motor.

111 is the center height of the motor.

4 should be the number of poles.

The parameters of this motor are as follows:
