YDT Series Three-Phase Consequent-Poles Asynchronous Motor for Fan and Pump

YDT Series Three-Phase Consequent-Poles Asynchronous Motor for Fan and Pump

Among the YDT series three-phase consequent-poles asynchronous motor specially matched for a load of fan blowers or pumps is an outgrowth from series Y series electric motors. The series electric motors are novel in design their rotational speed will decrease by degrees of quadratic relation with the increase in a load of fan blowers or pumps, and their torque properties: the power of the motor is directly proportional to the quadrate of rotational speed Due to it that they can reasonably match the corresponding power according to the complemental requirement of rotational speed, they can save a lot of energy, therefore may be rated as an ideal dynamic force for the fan blowers of load type. They are widely used in metallurgy, mining, textile, dyeing, chemical industry, light industry, architecture, civil facilities, and other departments with virtues of high efficiency, saving energy, low noise, little vibration, fine isolation reliable operation easy maintenance, etc.

YDT Series Three-Phase Consequent-Poles Asynchronous Motor Operating Conditions:

1 、Ambient temperature: to be altered with the change of seasons but do not exceed40℃

2、Altitude: to be used lower than 1,000 meters above sea level.

3、Rated frenquency:50HZ

4、Rated voltage:380V

5、Duty:continuous(s1)

6、Metod of starting: can be started directly on full voltage for all sizes of motors.

Three Phase Motor Overload Protection

If the motor is overloaded for a long time, and the temperature rise of the motor winding exceeds its allowable value, the insulating material of the motor will become brittle, the service life will be reduced, and the motor will be damaged in severe cases. The larger the overload current, the shorter the time to reach the allowable temperature rise. Commonly used overload protection components are thermal relays. The thermal relay can meet the following requirements: when the motor works at the rated current, the motor winding temperature rises to the rated temperature rise, and the thermal relay does not act; when the overload current is small, the thermal relay takes a long time to act, and the overload current is large. , the thermal relay will operate after a short period of time.

Due to thermal inertia, the thermal relay will not be affected by the short-term overload impulse current or short-circuit current of the motor and act instantaneously. Therefore, when using the thermal relay for overload protection, it must also be provided with short-circuit protection. And the rated current of the fuse melt selected for short-circuit protection should not exceed 4 times the rated current of the heating element of the thermal relay.

When the working environment temperature of the motor and the working environment temperature of the thermal relay is different, the reliability of the protection will be affected. There is a thermal relay using a thermistor as a measuring element, which can embed the thermal element in the motor winding and can measure the temperature rise of the motor winding more accurately. Overcurrent protection is widely used in DC motors or wound rotor asynchronous motors. For three-phase cage motors, short-circuit protection is not used because short-term overcurrent will not cause serious consequences.

Difference Between Single Phase Motor and Three Phase Motor

Difference	Single Phase Motor	Three Phase Motor
Power supply	The single-phase induction motor uses a single phase supply.	The three-phase induction motor uses three phase supply.
Starting mechanism	The single-phase motor is not self-starting, requiring external devices such as motor startups.	The three-phase motor is self-starting, without requiring any external devices.
Efficiency and consumption	According to single phase vs three phase motor power consumption and efficiency, the single-phase motor has low efficiency as only one winding has to carry all the current.	The three-phase motor has high efficiency because three windings are available to carry the current. Three-phase motor supplies use less amount of electrical power than single-phase motor supplies.
Features	The single-phase motor is simple in construction, reliable, and economical compared to three-phase induction motors.	The three-phase motor is complex in construction and costly.
Maintenance	The single-phase motor is easy to repair and maintain.	The three-phase motor is difficult to repair and maintain.
Size (for same power rating)	The single-phase motor is larger in size.	The three-phase motor is smaller in size.
Structure	The single-phase motor is simple and easy to manufacture.	The three-phase motor is more complicated to construct because of extra component involvement.
Motor rotation	In the single-phase motor, there is no mechanism to change the rotation.	The rotation of the three-phase motor can be changed easily by changing the phase sequence in the stator.
Output voltage levels	The single-phase motor delivers a voltage level of almost 230V.	The three-phase motor delivers a voltage level of almost 415V.
Starting torque	The single-phase motor offers a very limited starting torque.	The three-phase motor offers very high starting torque.
Power rating	The single-phase motor is made for a low power rating usually below 5kW.	The three-phase motor is made for a power rating above 5kW.
Application	According to the application of single phase and three phase induction motors, the single-phase motor mostly finds use in domestic appliances, and lighter loads such as blowers, vacuum cleaners, fans, centrifugal pumps, washing machines, grinders, toys, electric shavers, drilling machines, compressor, etc.	The three-phase induction motors are extensively employed in industrial and commercial drives since they are more rugged and economical in terms of operational efficiencies, such as lifts, cranes, hoists, large capacity exhaust fans, driving lathe machines, crushers, oil extracting mills, textile, etc.
