BERGER LAHR RSM canned motors

ASTRO is an official partner of Schneider Electric Automation (formerly Schneider Electric Motion) for BERGER LAHR canned motors – RSM 36 to RSM 63.

Synchronous motors for continuous operation: BERGER LAHR can motors are Berger Lahr's most widely used AC synchronous motors in the small to medium power range. They are manufactured in several sizes and electrical versions and run directly on the 50/60 Hz mains supply.

Overview of the original BERGER LAHR can motors currently available from ASTRO – these motors are newly manufactured:

• BERGER LAHR RSM 36/8 FG
• BERGER LAHR RSM 42/8 FG
• BERGER LAHR RSM 51/12 FG
• BERGER LAHR RSM 51/8 FG
• BERGER LAHR RSM 51/6 FG
• BERGER LAHR RSM 63/8 FG
• Further designs and
  individual requirements on request

 

Basic principle of designation: RSM XX/Y:

• RSM = Rotating Synchronous Motor. This is the series designation for compact, pole-changing synchronous motors from Berger Lahr.
• XX = Size / housing diameter in millimetres (rounded).
• Y = Number of poles (number of magnetic poles on the rotor).
• XX = Size / housing diameter in millimetres (rounded).
  This directly determines the rated speed of the motor at a given mains frequency (50 Hz or 60 Hz).
  
• Example BERGER LAHR RSM 36/8
  Size 36 mm, 8 poles, 375 rpm, remarks: Very compact design, ideal for precision engineering applications or device automation
• Example BERGER LAHR RSM 51/8
  Size 51 mm, 8 poles, 375 rpm, remarks: medium size, universal application, frequently used in laboratory and medical technology
• Example BERGER LAHR RSM 51/6
  Size 51 mm, 6 poles, 500 rpm, remarks: medium size, higher speed with the same housing and lower torque

 

Further information

• Defined performance data: These types each represent defined performance data (increasing dimensions and torque reserves).
• With and without gearbox: From the factory, variants with and without gearboxes were available; the modular concept allowed a precisely tailored selection for different load cases and installation situations.
• Power & torque (typical): depending on size, torques from the lower to medium cNm range; designed for continuous operation synchronised with the mains (S1), robust bearings and constant speed without complex control.
• Typical applications: Actuators in measurement and control technology, access systems, metering pumps, label dispensers, conveyor elements, laboratory and process equipment – wherever uniform, reliable rotary motion with manageable torque requirements is needed.
• Industrial significance and availability: The RSM series RSM 36/8, RSM 42/8, RSM 51/8, RSM 63/8 is considered the best-known and most widely used synchronous motor family from BERGER LAHR. In addition to standard versions, special variants are also available (e.g. with brakes, gearboxes, special shafts/connections).

 

Consulting, ordering and delivery by ASTRO

As an official partner of Schneider Electric Automation, ASTRO provides consultation, accepts orders, and supplies the can motors. In addition, customer-specific modifications can be made based on the original Berger Lahr squirrel cage motors.

• Customised modifications: In addition to the standard models, ASTRO offers options for cable lengths, plug connections according to customer specifications, rotor shaft designs and other technical customer requirements. We also offer combinations with the company's extensive gearbox range.
• Practical advantage: This allows the motors to be integrated directly into existing systems without any modifications to peripherals or cabling.
