1) Cooling type E is available for sizes 4, 6 and 8 only upon request.
2) Cooling types O and P are only available in size 9.

Cooling types C and P

The built-in fan module increases the nominal torque (MN), nominal current (IN), stall torque (M0) and stall current (I0) by approx. 30% compared to the respective motors with cooling type A (for cooling type C) or cooling type O (for cooling type P).


Size (c)

8LS three-phase synchronous motors are available in various sizes (2, A, 3 ... 9). These differ in dimensions (especially flange dimensions) and power data. The different sizes are distinguished by a number (c) in the model number. The larger this number, the larger the flange dimensions and power data of the respective motor.

Motor encoder systems (ee)

8LS three-phase synchronous motors are available with EnDat encoders as well as resolvers. The encoder system is listed as part of the model number in the form of a 2-digit code (ee).

Motors with "S encoders" (functional safety) cannot be combined with gearboxes!

Resolver

A resolver is an analog encoder system. Resolvers are particularly robust against vibrations and high operating temperatures. A disadvantage is the low accuracy of 6-10 arcmin. Furthermore, no multi-turn variant with resolvers is possible.

Digital encoders

Digital encoders use a serial transfer protocol. This protocol is called EnDat. The EnDat protocol is a developed standard that incorporates the advantages of absolute and incremental position measurement and also offers a read/write parameter memory in the encoder. The embedded parameter chip is stored by B&R in this encoder memory. This data and the B&R ACOPOS systems form a plug-and-play drive solution. Absolute positioning can be used within a revolution with the single-turn variants. A homing procedure is not required because of the absolute position measurement. For applications where the motor covers several revolutions for positioning, a multi-turn encoder that can save up to 65535 revolutions can be used. A solution with a single-turn encoder variant with a homing procedure is also possible. In EnDat 2.1 analog/digital sampling, a very fine resolution is achieved by the evaluation modules developed by B&R.

The inductive encoders with product IDs "EA" and "EB" replace the encoder types with model numbers "E2" and "E3". These encoders should be used in all new applications.

The "EB" encoder type requires the following versions of our servo drives or inverter modules:

(ACP10_SYS or firmware version)

  • ACOPOS: Starting with V2.090 from 2008-09-18
  • ACOPOSmulti: Starting with V2.031 from 2008-01-17

For older basic versions of the ACOPOS firmware, using the new encoder is possible starting with V0.556 (from 2010-07-22) for ACOPOS with AC110 (CAN bus) and starting with V1.249 (from 2010-07-22) for ACOPOS with AC112/114.

All other lengths for size 7 and all size 8 motors are equipped with connector size 1.5 and therefore not suitable for the single-cable solution (hybrid). Size 9 motors (cooling type O/P) are only available with terminal boxes.

Single-cable solution (hybrid) - Temperature evaluation

In the case of motors with the single-cable solution (hybrid connector), the temperature signal is not transmitted via two separate lines as before. Instead, it is transmitted digitally via the encoder interface.

The following conditions must be met by the drives in order to operate a motor with a hybrid connector:

  • For ACOPOSmulti: the cable cover must be designed for operation with a hybrid cable (with cable cutout; delivered 2015 or later)
  • For ACOPOSmulti with SafeMOTION: the operating system (NC version) must be set to V2.48.0 or higher; the Safety Release must be V1.9 or higher
  • For all drives: the operating system (NC version) must be set to V2.42.2 or higher

NOTE: If the conditions listed above are not met, temperature evaluation on the drive will not work.

Connection direction (ff) for 8LSA/8LSC

Connection direction (ff) for 8LSA/8LSC

The uniform connection technology, the pre-assembled cables and the embedded parameter chip allow "plug and play" operation of the power transmission system. The angled connectors can be swiveled for maximum cabling flexibility. Thanks to the digital signal transmission, B&R's innovative and sturdy single-cable solution (hybrid motor cables) can be used, which combines servo feedback and power for streamlined installation. The winding insulation of motors with an attachment cable and servo drive from B&R are tested extensively in accordance with IEC TS 60034-25 limit curves and are certified by the TÜV in the area of safety technology.

3 different connection options are available for 8LSA and 8LSC three-phase synchronous motors.

One connection each for power and signal is provided with the angled and straight built-in connector. The 2 available options differ in the connection direction (straight or angled).

Oil seal (ff)

All 8LS three-phase synchronous motors are available with an optional Form A oil seal in accordance with DIN 3760.

When equipped with an oil seal, the motors have IP65 protection in accordance with EN 60034-5.

Proper lubrication of the oil seal must be ensured throughout the entire service life of the motor.

For this reason, mounting a gearbox on motors with an oil seal is not permitted!

Special motor options (gg)

8LSA and 8LSC three-phase synchronous motors with sizes 4 - 8 are available with special option "Reinforced A-side bearing". A special brake is required for motors with a reinforced bearing and holding brake.

In addition to the 24 VDC standard fan (8LSC / 8LSP) a 230 VAC fan is available for 8LSC as a special option. Other special motor options must be arranged with B&R.

Example order: Motor with reinforced A-side bearing without brake

For an 8LSA55 with D0 encoder with the connection type "single-cable solution, angled (swivel connector)", the following selection is made: no brake, no oil seal, with shaft key. Motor option (ff) = S1. A reinforced A-side bearing is also needed. Special motor option (gg) for 8LSA = 04.

The order code is: 8LSA55.D0030S104-3

For an 8LSC55 with D0 encoder with the connection type "single-cable solution, angled (swivel connector)", the following selection is made: no brake, no oil seal, with shaft key. Motor option (ff) = D1. A reinforced A-side bearing is also needed. Special motor option (gg) for 8LSC = 11.

The order code is: 8LSC55.D0030S111-3

Example order: Motor with reinforced A-side bearing with special brake

For an 8LSA55 with E0 encoder and connection direction angled (swivel connector), a reinforced A-side bearing is needed. Special motor option (gg) for 8LSA = 04. The following selection is still made: Special brake, no oil seal, with shaft key. Motor option (ff) = DD

The order code is: 8LSA55.E0030DD04-3

For an 8LSC55 with E0 encoder and connection direction angled (swivel connector), a reinforced A-side bearing is needed. Special motor option (gg) for 8LSC = 11. The following selection is made: no brake, no oil seal, with shaft key. Motor option (ff) = DD .

The order code is: 8LSC55.E0030DD11-3

Motor version (h)

The motor version is automatically specified by the configurator and can be seen in the technical data.

Example order 1

A three-phase synchronous motor of type 8LSA45 with a nominal speed of 3000 rpm was selected for an application. Because of the construction, the cables can only be connected on the top of the motor ("top" connection direction). The motor should also be equipped with a holding brake, a keyed shaft and a 32-line EnDat single-turn encoder.

The code (ee) for the encoder system is EA.

The (nnn) code for a nominal speed of 3000 rpm is 030.

The code (ff) for the other options (oil seal, holding brake, keyed shaft and connection direction) is C3.

The model number for the required motor is 8LSA45.EA030C300-3

Example order 2

A three-phase synchronous motor of type 8LSA56 with a nominal speed of 4500 rpm was selected for an application. Because of the construction, the cables can only be connected on the back of the motor (swivel connectors), and need to be as compact as possible, so the single-cable (hybrid) solution is desired. The motor should also be equipped with a holding brake, a smooth shaft, an oil seal and a 32-line EnDat multi-turn encoder.

The code (ee) for the encoder system is DB.

The code (nnn) for a nominal speed of 4500 rpm is 045.

The code (ff) for the other options (oil seal, holding brake, smooth shaft end and angled hybrid cable) is S8.

The model number for the required motor is therefore 8LSA56.DB045S800-3.
