FOR ENERGY SAVING, USE ENNENG PMSM MOTOR.

1. Brief introduction

TYP series high-efficiency permanent magnet variable frequency synchronous motor must be used together with the permanent magnet motor frequency converter. The rotor of this series motor is of permanent magnet built-in structure. The series motors have a certain salient pole torque due to the special design of magnetic circuits with different quadrature and straight shafts. Therefore, the frequency converter needs to use the maximum torque/current ratio control mode to control the work, so that the series of motors have a high power factor in the full speed regulation range, low operating current, and low copper consumption.

The speed of the TYP series high-efficiency permanent magnet variable frequency synchronous motor is synchronized with the stator rotating magnetic field, and there is no slip, saving the slip power, so the synchronous motor has high efficiency and obvious energy saving effect in the full-speed regulation range.

TYP series motor is widely used in injection molding machines, air compressors, pipe-making equipment, hydraulic machinery, food machinery, cement pipe-making machine, plastic extruder, wire drawing machines and pharmaceutical equipment, and other places.

Our company has a specialized control cabinet for this series of products, which can be customized according to user requirements.

5.Attention:

1. TYP series high efficiency permanent magnet variable frequency synchronous motor must be used together with the permanent magnet motor frequency converter. It is forbidden to connect to the three-phase current directly without the converter;
2. TYP series high efficiency permanent magnet variable frequency synchronous motor frequency converter must adopt the maximum torque/current ratio control mode, otherwise it cannot reach the optimal working state, which will cause the decline of the motor power factor and torque reduction;
3. TYP series high efficiency permanent magnet variable frequency synchronous motor adopts Y connection, and Y/△ connection is not allowed.

6.Energy-saving principle of permanent magnet synchronous motor:

1. high efficiency: the average power saving is more than 10% compared with Y2 series motors. Generally when the asynchronous motor is below 60% of the rated load, the decrease of efficiency is fast, and the efficiency is very low when motor runs with light load. The efficiency of asynchronous motor decreases rapidly with the decrease of speed, so the efficiency of asynchronous motor is very low at low speed and load. TYP series high efficiency permanent magnet variable frequency synchronous motor is in the high efficiency zone ranging from 20% to 110% of rated load. The electric saving rate of permanent magnet synchronous motor (PMSM) is 10% ~ 40%, tested by many factories under different working conditions.
2. high power factor: the measured value of rated state is close to the limit value 1.0, all above 0.95. The power factor curve and efficiency curve of TYP series high efficiency permanent magnet variable frequency synchronous motor are high and flat; High power factor and low stator current can reduce stator copper consumption and improve efficiency.
3. small current: this series of motor adopts rotor magnetic steel built-in structure, with a certain salient pole torque, adopting the maximum torque/current ratio control mode, so that the motor has a high power factor in the full speed regulation range, and motor current decreased significantly. According to the actual measurement, compared with the asynchronous motor, the stator current of permanent magnet motor can be reduced by 15%~30%. Since the motor current is significantly reduced, which reduces the loss in cable transmission, and is equal to the expansion of cable capacity, and the transmission cable can be equipped with more motors.
4. run without slip, and speed is stable: TYP series motor is a synchronous motor, the rotating speed of the motor is only related to the power frequency: motor speed is synchronous with the stator rotating magnetic speed, not affected by voltage fluctuation, load size, so it won’t lose speed, slip, has no power loss, which will improve the efficiency and control accuracy.
5. temperature rise 15 ~ 20 ℃ lower: TYP series synchronous motor has high efficiency and low loss, so temperature rise is low. When measured in the same conditions, the working temperature of permanent magnet motor is 15 ~ 20 ℃ lower than that of the asynchronous motor.
6. Temperature rise comparison

7. installation of motor

1. Coupling, spur gear and belt pulley are allowed to drive the motor.
2. When belt driving is adopted, the motor shaft center line is parallel to the load shaft center line, and the belt center line is required to be perpendicular to the shaft center line; When coupling driving, the motor shaft center line and load shaft center line should coincide.
3. Good ventilation and cooling conditions shall be ensured for motor installation.

8. Running of motor

1. The motor shall be properly grounded, and the junction box shall be equipped with grounding device. If necessary, it can also be grounded by use of the motor anchor fastening bolts.
2. There are 6 terminals on the motor terminal board. A) If the stator windings are Y-connected, so only three wires are drawn out from terminals, which are respectively connected to the terminals of U1, V1 and W1 on the junction plate. The power lines A, B and C are connected to these three terminals. U2, V2 and W2 will not be connected. B) If there is no Y connection of the stator winding, six wires with wiring terminals shall be drawn out and connected to the terminals of U1, V1, W1, W2, U2 and V2; respectively; connect W2, U2 and V2 with the connection straps on junction plate to form Y connection. The connection is shown below picture. Winding Y connect draw 3 wires; Winding not Y-connect draw 6 wires;  Winding Y-connect, draw 6 wires
3. When the three-phase power is connected with the terminal posts U1, V1 and W1 respectively in phase sequence A, B and C, the motor’s rotation direction is clockwise seen from the shaft extension end. If arbitrarily replace two power phase sequences, and the motor’s rotation will become counterclockwise.
4. The motor of continuous working is not allowed to overload.
5. There should be no intermittent or abnormal sound or vibration when motor runs with load or without, and bearing temperature should not exceed 95 ℃.

9. Motor maintenance and repair

1. The environment should always be kept dry, and motor surface should be kept clean; air inlet should not be obstructed by dust, fiber and others.
2. When the protection alarms, the cause of the fault shall be found out and removed before it can be put into operation.
3. When the motor is stopped for inspection, it cannot be operated until the motor stops completely.
4. In order to ensure good lubrication of the motor in operation, when the motor operate for about 4000 hours, the grease shall be supplemented or replaced (the closed bearing does not need to replace the grease in the service life). If the bearing is found to be overheated or the grease deteriorates during operation, the grease shall be replaced in time. When replacing the grease, remove the old grease and clean the oil groove of the bearing and bearing cover with gasoline. Then add small and medium-sized motor grease and fill two-thirds of the gap between the inner and outer rings of the bearing.
5. When the life of the bearing ends, the vibration and noise of the motor will increase significantly. When the radial clearance of the bearing reaches the value of following table, the bearing shall be replaced.

Bearing specification: speed≤2000 r/min

Bearing specification: speed 2000～3600r/min

6. Maintenance of TYP series synchronous motor shall be carried out by qualified units or personnel who know matters of attention of TYP series synchronous motor.
7. When disassembling the motor, the rotor can be removed from the shaft extension end or the non-shaft extension end. If it is not necessary to remove the fan, it is more convenient to remove the rotor from the non-shaft extension end. When the rotor is removed from the stator, damage to the stator winding or insulation should be prevented.
8. When replacing the winding, the form, size, number of windings and wire gauge of the original winding must be recorded. Random replacement of the original windings will often deteriorate one or several motor performances, or even make motor impossible to use.

10.Storage and transportation of motor

1. The motor should be kept dry in storage, and avoid sharp changes in ambient temperature.
2. Motors should not be piled up too high for storage, in case of damage to the lower motor.
3. The storage and transportation should prevent the motor from dumping or inverting.
