2.3 Lifting All TECHTOP motors above 25 kg are equipped with lifting lugs or eyebolts. Only the main lifting lugs or eyebolts of the motor should be used for lifting the motor. They must not be used to lift the motor when it is attached to other equipment. -
Page 6: Machine Weight
The total machine weight can vary within the same frame size (center height) depending on different output, mounting arrangement and auxiliaries. The following table shows estimated maximum weights for machines in their basic versions as a function of frame material. The actual weight of all TECHTOP’s motors is shown on the catalogue. Aluminum... -

3. INSTALLATION AND COMMISSIONING WARNING! Disconnect and lock out before working on the motor or the driven equipment. 3.1 General All rating plate values must be carefully checked to ensure that the motor protection and connection will be properly done. WARNING! In case of motors mounted with the shaft upwards and water or liquids are expected to go down along the shaft, the user must take in account to mount some means capable of preventing it. -
Page 8: Foundation
WARNING! The motor frame must be grounded and the windings should be discharged against the frame immediately after each measurement to avoid risk of electrical shock. If the reference resistance value is not attained, the winding is too damp and must be oven dried. The oven temperature should be 90°C for 12-16 hours followed by 105°C for 6-8 hours. -
Page 9: Slide Rails And Belt Drives
Re-check the alignment after final tightening of the bolts or studs. 3.6 Slide rails and belt drives Fasten the motor to the slide rails as shown in Figure 2. Place the slide rails horizontally on the same level. Check that the motor shaft is parallel with the drive shaft. Belts must be tensioned according to the instructions of the supplier of the driven equipment. WARNING! Excessive belt tension will damage bearings and can cause shaft damage. -
Page 10: Connection Of Auxiliaries
The voltage and connection are stamped on the terminal box cover. Direct-on-line starting (DOL): Y or D winding connections may be used. For example, 690 VY, 400 VD indicates Y-connection for 690 V and D-connection for 400 V. WARNING! from 10KW Start/Delta (Y/D) starting is recommended Star/Delta starting (Y/D): The supply voltage must be equal to the rated voltage of the motor when using a D-connection. -
Page 11: Cooling
WARNING! Ignoring any of given instructions or maintenance of the apparatus may jeopardize the safety and thus prevents the use of the machine. 4.2 Cooling Check that the motor has sufficient airflow. Ensure that no nearby objects or direct sunshine radiate additional heat to the motor. For flange mounted motors (e.g. -
Page 12: General Inspection
Grease can cause skin irritation and eye inflammation. Follow all safety precautions specified by the gease manufacturer. Bearing types are specified in the respective product catalogs. Reliability is a vital issue for bearing lubrication intervals. TECHTOP uses mainly the L1-principle (i.e. that 99% of the motors are certain to make the life time) for lubrication. -

These values are valid for permitted load values given in the product catalog. Depending on application and load conditions, see the applicable product catalog or contact TECHTOP. Data above reported will be in compliance with item 5.2, and are refered at the following motor working conditions, ambient temperature 25°C, max bearing working temperature 80°C. -
Page 14: Motors With Regreasable Bearings
Bearings lifetime values below reported, are valid for permitted load values given in the product catalog. Depending on application and load conditions, see the applicable product catalog or contact TECHTOP. Data above reported will be in compliance with item 5.2, and are refered at the following motor working conditions, ambient temperature 25°C, max bearing working temperature 80°C. -
Page 15: Lubrication Intervals And Amounts
As a guide, adequate lubrication for motors with regreasable bearings can be achieved for the following duration, according to L1. For duties with higher ambient temperatures please contact TECHTOP. The formula to change the L1 values roughly to L10 values: L10 = 2.7 x L1. - Page 16 Lubrication intervals according to L1 principle Amount of 500-900 Frame size grease 3600 rpm 3000 rpm 1800 rpm 1500 rpm 1000 rpm g/bearing Ball bearings -- Lubrication intervals in duty hour 10.000 13.000 18.000 21.000 25.000 28.000 9.000 11.000 17.000 19.000 23.000 26.500...

7.1 Noise levels Most of TECHTOP’s motors have a sound pressure level not exceeding 80 dB(A) at 50 Hz. Values for specific machines can be found in the relevant product catalogues. At 60 Hz sinusoidal supply the values are approximately 4 dB(A) higher compared to 50 Hz values in product catalogues. -
