8LT direct drive torque motors

五分彩骗局步骤图direct drive torque motors from the 8lt series are permanently excited torque motors for applications that require extraordinary dynamic characteristics and positioning precision as well as compact size and reduced weight. these are available in self-cooling or externally-cooled format.

五分彩骗局步骤图the 8lt series torque motors provide the user with the highest degree of flexibility - the ideal basis for mechatronic and efficient machine design.

五分彩骗局步骤图all motor components are designed in such a way that saves maintenance.

五分彩骗局步骤图this motor series features a relatively compact structure with a higher degree of rigidity and more dynamic properties as well as low detent torque. the externally-cooled format additionally ensures intensive surface cooling - the motor does not cause the environment around it to heat up.

五分彩骗局步骤图the 8lt torque motors are designed as complete motors. unlike built-in motors, there is no need to install bearings and encoders.

advantages of b&r direct drives for your application:

  • Easy to install
  • Small installation dimensions
  • Extremely easy to service
  • Low costs
  • High overload capability/peak torque
  • Also available with hollow shaft
  • Very good control properties because of low cogging torque
  • Available with encoders for functional safety
  • When used as a direct drive: No mechanical transfer elements that are subject to wear in the power transmission system, therefore high level of availability and no elasticity in the power transmission system
Connection type

五分彩骗局步骤图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, which provides the maximum amount of flexibility during cabling.

Embedded parameter chip

All relevant mechanical and electrical information and data is stored in the EnDat encoder used for 8LT three-phase synchronous motors. This means that the user doesn't have to configure settings on the servo drive in the field. As soon as the encoder is connected to the servo drive and power is applied to the electronics, the motor is automatically identified. The motor sends its nominal parameters and limit parameters to the servo drive. The drive then automatically determines the current limits and current control parameters required for optimal control of the motor. The only things that the user has to optimize are the speed and position controllers. The integrated commissioning environment in B&R Automation StudioTM provides all necessary support.

五分彩骗局步骤图in addition to assistance during commissioning, routine service work is also simplified, and motors can be exchanged without having to take extra time to set parameters.

Cooling / construction type

8lt three-phase synchronous motors with cooling / construction type a are self-cooling and are equipped with a iso output flange. the motors must be installed on the cooling surface (flange).

五分彩骗局步骤图8lt three-phase synchronous motors with cooling/construction type b are self-cooling hollow shaft motors.

8LT three-phase synchronous motors with cooling / construction type J are based on motors with cooling type A and are liquid-cooled. The liquid-cooling increases the nominal torque (MN), nominal current (IN), stall torque (M0) and stall current (I0) by 70% as compared to the respective motors with cooling type A.

8lt three-phase synchronous motors with cooling / construction type k are based on motors with cooling type b and are liquid-cooled.

8lt three-phase synchronous motors with cooling / construction type q are self-cooling and have a shaft with a blind hole. the motors must be installed on the cooling surface (flange).

8LT three-phase synchronous motors with cooling / construction type S are based on motors with cooling type Q and are liquid-cooled. The liquid-cooling increases the nominal torque (MN), nominal current (IN), stall torque (M0) and stall current (I0五分彩骗局步骤图) by 70% as compared to the respective motors with cooling type Q.

Feedback systems specified to meet your needs

五分彩骗局步骤图8lt synchronous motors are equipped with high resolution endat encoders. a model is also available with multi-turn encoder. they allow operation without requiring homing procedures or additional measurement systems on the workpiece. the absolute encoder functions without a battery and is therefore absolutely maintenance-free.

五分彩骗局步骤图with hollow shaft motors, endat 2.2 encoders with distance-coded reference marks for absolute position are used.

五分彩骗局步骤图all 8lt motors rotate clockwise (when looking at the shaft from the front) with th exception of the counterclockwise 8ltb/ 8ltk hollow shaft motors.

Load capacity of the shaft end and bearings

8lt three-phase synchronous motors are equipped with grooved ball bearings that are sealed on both sides and lubricated. bearing elements must not be subjected to shocks or impacts! incorrect handling will reduce the service life and result in damage to the bearings.

Motor options

五分彩骗局步骤图8lt three-phase synchronous motors can be delivered with the following options depending on the cooling type and size:

  • With various nominal speeds
  • With or without an oil seal
  • With two different connection directions for the motor connector

The nominal speed is listed as part of the model number in the form of a 3-digit code (nnn). The code corresponds with the nominal speed divided by 100 and preceded by a zero. For example, 1000 rpm would correspond with code 010. If the nominal speed is below 100 rpm, the "nominal speed" part of the order code has an "A" as the first character and then the nominal speed is listed as follows. A speed of 80 rpm corresponds to A08.

the respective combination of other motor options is listed as part of the model number in the form of a 2-digit code (ff).
