Flyer HW Liquid cooled Issue 2

Product catalog summary

Overview: This document provides comprehensive technical specifications and operational guidelines for SEM Limited's Asynchronous Spindle Motors (ASM), covering both solid and hollow shaft models.

General Technical Information: The motors are equipped with HEIDENHAIN rotary encoders for speed measurement. Solid shaft motors use the ERN 1381 encoder with 1,024 lines, while hollow shaft motors and the ASM 200M/18000rpm use the ERM 280 encoder with 600 lines.

Specifications: Motors are designed to operate without thermal insulation, with a maximum temperature rise of 105 K and an ambient temperature limit of 40°C. Torque reduction is necessary if thermally insulated to prevent overheating.

Shaft Bearing: Maintenance-free bearings are used, with options for standard or high-specification spindle bearings, which allow for higher radial forces and speeds.

Mechanical Life: The nominal bearing service life is 10,000 hours, dependent on shaft load and speed.

Shaft End: Motors have a shaft extension per DIN 748-1, with options for plain or keyed shafts.

Hollow-Shaft Motors: Suitable for direct spindle mounting and allow coolant passage through a rotating manifold.

Mechanical Data: Motors are designed for flange/base mounting (IM B35) with protection class IP 54 and vibration severity grade SR.

Thermal Specifications: Motors feature separate cooling via an integrated fan and temperature monitoring with a KTY 84-130 thermistor.

Performance Data: Detailed tables provide rated power, speed, torque, and current for various models, highlighting differences between standard and spindle bearings.

Power and Torque Characteristics: Performance curves illustrate power and torque across different duty cycles and speeds for models like ASM 200 M, ASM 200 L, and ASM 200 U.

Model Specifications:

ASM 260 M, MH: Power outputs range from 4.0 kW to 32.0 kW depending on the duty cycle (S1, S6-60%, S6-40%, S6-25%). Torque varies from 3.2 Nm to 203.7 Nm.
ASM 200 UH: Power ranges from 4.0 kW to 17.0 kW, with torque between 2.5 Nm and 108.6 Nm.
ASM 260 L, LH: Power outputs range from 8.0 kW to 37.0 kW, with torque from 6.4 Nm to 235.5 Nm.
ASM 260 U: Provides power from 18.0 kW to 48.0 kW, with torque between 17.2 Nm and 305.6 Nm.
ASM 260 W: Power ranges from 4.0 kW to 22.0 kW, with torque from 3.8 Nm to 280.1 Nm.
ASM 320 M: Offers power from 19.5 kW to 53.0 kW, with torque between 18.6 Nm and 337.4 Nm.
ASM 320 L: Power outputs range from 21.0 kW to 66.0 kW, with torque from 21.0 Nm to 420.2 Nm.

Performance Curves: Each motor model includes power and torque performance curves, illustrating the relationship between speed, power, and torque across different duty cycles.

Critical Information: The document emphasizes the importance of selecting the appropriate duty cycle to optimize motor performance and efficiency. It also highlights the need to consider current ratings to ensure compatibility with electrical systems.

Asynchronous Motors General technical information Speed measurement An integrated rotary encoder from HEIDENHAIN measures the shaft speed. • Motors with solid shaft are fitted with an ERN 1381 encoder with 1 024 lines. • Motors with a hollow shaft and the ASM ERM 280 encoder with 600 lines. curves apply when motors are mounted without thermal insulation. All ratings are based on a maximum temperature rise of 105 K on the winding with a maximum am- bient temperature of 40 °C. If the motor is mounted so that it is thermally insulated, it is necessary to reduce the motor torque in order to avoid...
