8LSA

Cooling type 8LSA is self-cooling and has a slim, elongated design.

These motors must be attached to the machine with the mounting flange, which also serves as a cooling surface.

8LSC

Cooling type 8LSC is based on motors with cooling type 8LSA. These motors are externally cooled and differ only by a fan assembly mounted in the area of the B-side bearing.

These motors must be attached to the machine with the mounting flange, which also serves as a cooling surface.

Depending on the mounting situation, the attached fan assembly increases the nominal torque (MN), nominal current (IN), stall torque (M0) and stall current (I0) by 30% compared to the motors with cooling type 8LSA.

8LSO

Cooling type 8LSO is self-cooling and has a slim, elongated design.

These motors can be mounted to the machine with the mounting flange, which also serves as a cooling surface, or with the mounting base. If the motor is only mounted with the mounting base and not with the mounting flange, the continuous power is reduced in S1 operation.

8LSP

Cooling type 8LSP is based on motors with cooling type 8LSO. These motors are externally cooled and differ only by a fan assembly mounted in the area of the B-side bearing.

These motors can be mounted to the machine with the mounting flange, which also serves as a cooling surface, or with the mounting base. If the motor is only mounted with the mounting base and not with the mounting flange, the continuous power is reduced in S1 operation.

Depending on the mounting situation, the attached fan assembly increases the nominal torque (MN), nominal current (IN), stall torque (M0) and stall current (I0) by 30% compared to the motors with cooling type 8LSO.

For transport reasons, this cooling type always has mounting base.

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

Resolver

A resolver is an analog encoder system. Resolvers are particularly robust against vibrations and high operating temperatures. Their disadvantage is the low precision of 6-10 arcminutes. There is still no multi-turn variant with resolvers.

Digital encoders - EnDat

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.

For the advanced, fully digital EnDat 2.2 protocol, the positions are generated directly in the encoder and communicated serially with the drive system. This transfer is very robust in relation to disturbances and is even certified for safety applications.

EnDat 2.2 is therefore to be preferred over the older EnDat 2.1 variant.

    Availability of single-cable solution (hybrid)

    Availability of single-cable solution (hybrid)

    There is no single-cable solution (hybrid) available for resolvers and EnDat 2.1 encoders.

    The single-cable solution (hybrid) is only possible for motors with connector size 1.0 (built-in connector on the motor side) and therefore generally up to size/length 65.

    The following exceptions apply to individual motors with size/length 5A, 5B and 5C. The listed motors are therefore not available as a single-cable solution (hybrid).

    Reinforced A-side bearing

    8LSA and 8LSC three-phase synchronous motors with sizes 4 - 8 are available with special motor option "Reinforced A-side bearing".
    The reinforced A-side bearing allows increased radial and axial forces (Fr and Fa) to be absorbed at the shaft end. For specifications for determining the permissible radial and axial forces, see the corresponding motor data.

    Motors with special motor option "reinforced A-side bearing" have increased values for the dimensions of the motor shaft and the total length (in relation to motors with standard bearings).

    For the exact dimensions, see the technical data of the respective 8LS three-phase synchronous motors.

    Special-purpose holding brake for reinforced A-side bearing

    Special-purpose holding brake for reinforced A-side bearing

    A special-purpose holding brake is required for special motor option "Reinforced A-side bearing" in conjunction with a holding brake.

    The holding brake is a permanent magnet brake and can be controlled by the B&R drive system. Based on principle, this type of holding brake exhibits a minimal amount of backlash. Voltage (see the technical data) must be applied to release the brake.

    The brake is designed as a holding brake. It not permitted to be used for operational braking! Under these conditions, the brake has a service life of approximately 5,000,000 cycles (opening and closing the brake is one cycle). Loaded braking during an emergency stop is permitted but reduces its service life.

    The required brake holding torque is determined based on the actual load torque. It is recommended by the brake manufacturer to take into account a safety factor of 2.

    The holding brake is not intended for normal braking. The maximum motor torque far exceeds the holding torque for the brake.

    If the holding brake should be used for the purpose of protecting personnel, the user must check via the MTTF values of the respective holding brake whether the performance level per EN ISO 13849 required for the respective application can be achieved with this holding brake. B&R recommends cyclical function testing of the holding brake.

    The motor version is specified as a code (h) in the order number. Motor version 3 is currently valid.

    Example order 1

    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 side 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 order number for the necessary motor is therefore 8LSA45.EA030C300-3.

    Example order 2

    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, cables can only be connected to the rear of the motor (swivel connectors). They should also take up as little space as possible. The single-cable solution (hybrid) is desired. The motor should also be equipped with a holding brake, smooth shaft, oil seal and 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 single-cable solution, swivel connector) is S8.

    The order number for the necessary motor is therefore 8LSA56.DB045S800-3.
