AB 1326AB High Performance AC Servomotors
Product Overview: 1326AB series servo motors are high-performance three-phase brushless AC synchronous motors, suitable for 1391 AC servo controller. They are equipped with standard features such as permanent magnet rotor, sinusoidal winding stator, brushless resolver feedback, etc., with protection class up to IP65 (except in some cases), and are available in a variety of optional configurations to meet different industrial needs.
Product Details
Model Number Description: The model number contains information about the motor type, mounting method, braking, etc. For example, for 1326AB - A1G, ‘A’ stands for a specific motor type, ‘1’ indicates the stack length within the frame dimensions, and ‘G ‘ relates to mounting and shaft related descriptions.
Performance Parameters: Performance data are given for different motor-amplifier combinations, such as continuous blocking torque, peak blocking torque, rated speed, etc. Typical speed-torque curves are also provided, defining rated and intermittent operation areas. Special order motors have specific performance specifications.
Dimensional specifications: Detailed list of mounting dimensions for the different motor series (A, B, C series), including face flange mounting and shaft extension dimensions, etc., as well as information on motor cable dimensions.
Optional Configurations: Provide a variety of optional configurations, such as integrated holding brake (90V DC or 24V DC coil), braking power supply, shaft oil seal kits, different types of feedback devices and mounting kits, junction box kits, fan cooling kits, etc., and the configurations have the corresponding technical specifications and features.
Application Guide: Provide users with selection steps to determine the motor speed and torque requirements according to the application, calculate the system inertia, and select the motor that meets the conditions. For different transmission systems such as screw, rack and pinion, conveyor belt, etc., the formulae and typical data for calculating motor speed, torque and system inertia are given. It also provides data tables for different application scenarios (e.g. point positioning, machine tool positioning, etc.) to help users make accurate selections.
Installation and wiring: When installing, it is necessary to pay attention to the installation direction of the motor, environmental conditions, etc. Some operations may affect the motor protection level. Detailed description of the various types of cables (such as commutation cable, power cable, etc.) pin definition and connection mode, to facilitate the user to make electrical connections .
Installation Considerations
Installation environment: The motors have a standard protection rating of IP65 against harsh environments when using the shaft sealing option, but this rating is lost when using externally mounted encoder/rotary transformer feedback or fan kits. The motor is suitable for use in contamination level 2 environments and should be installed to avoid specialised environments such as oily, corrosive, high temperatures, etc., or if this is not possible, additional protection will be required. At the same time, make sure that the altitude of the motor's installation location does not exceed the specified values to avoid factors such as air pressure affecting the motor's performance.
Motor Installation: The motor can be installed vertically with the shaft up or down. When installing the motor, make sure that the mounting surface of the motor is flat and stable, and avoid vibration and shock. For different series of motors (e.g. A, B, C series), pay attention to the differences in their mounting dimensions, and install them in accordance with the dimensional specifications in the manual to ensure that the mounting holes are aligned to avoid forcible installation resulting in damage to the motor or mounting components. During the installation process, if tools are needed, be careful to avoid damaging the motor shell and internal parts.
Accessory Installation: When installing the Integrated Brake, pay attention to the type of brake (90V DC or 24V DC coil) and the suitability of the motor, and follow the correct installation procedures. The brake is mainly used for holding stationary loads and emergency braking. When using the brake, pay attention to its limitations, e.g., when used as a parking brake, the number of times it is energised/de-energised must not exceed 90 times per hour. Ensure that the oil seal is in place when installing the shaft oil seal kit, which is suitable for occasional contact of the motor shaft with oil splashes and is not suitable for scenarios where the motor shaft is partially or completely submerged in oil. When installing an encoder or resolver feedback device, use the appropriate mounting kit for the different series of motors, e.g. 1326AB - MOD - Mxx series. Note that the use of these kits may result in the motor losing its IP65 protection rating.
Wiring Regulations: Strictly follow the cable wiring information when wiring, different types of cables (e.g. 1326 - CFUxx, 1326 - CPABxx, etc.) have different pin definitions and connection methods, ensure that they are connected correctly to avoid mismatched wiring which could lead to failure or damage to the motor. All cables should be hung or laid flat for 24 hours prior to installation to allow the conductors to ‘slacken’ to their natural state and prevent internal twisting. For extended length cables (1326ES series), use with 1391B - ES or 1391 - DES drives.
