High-performance Spindle Motor SJ-D Series

SJ-D Series
  • Motor energy loss has been significantly reduced by optimizing the magnetic circuit.
  • High-speed bearing incorporated as a standard feature helps to achieve higher speed, lower vibration and improved durability.
  • Range:
    Normal SJ-D Series 3.7 to 11 [kW]
    Compact & light SJ-DJ Series 5.5 to 15 [kW]
  • Maximum speed 10,000 or 12,000 [r/min]

High-output, High-torque Spindle Motor SJ-DG Series

SJ-DG Series
  • Addition of S3 rating (%ED rating) has improved output and torque acceleration/deceleration characteristics.
  • Balance adjustment ring has been added to the counter-load side for fine tuning.
  • Range:
    S3 rating: 5.5 to 15 [kW]
  • Maximum speed 10,000 or 12,000 [r/min]

Low-inertia, High-speed Spindle Motor SJ-DL Series

SJ-DL Series
  • The spindle motors are dedicated to tapping machines requiring faster drilling and tapping.
  • The latest design technologies have made it possible to attain lower vibration and greater rigidity even with the lighter weight.
  • Range:
    0.75 to 7.5 [kW]

Built-in Spindle Motor SJ-BG Series

SJ-BG Series
  • The electrical design has been optimized to increase the continuous rated torque per unit volume, contributing to the downsizing of spindle units.
  • Options for mold specification and cooling jacket specification are prepared.

Tool Spindle Motor HG-JR Series

HG-JR Series
  • Compact tool spindle motors are designed to have the small, high-output characteristics of servo motors yet offer high-speed rotation (8,000r/min). These motors contribute to downsizing spindle size, like rotary tool spindles.
  • Range 0.75 to 1.5 [kW]
  • Maximum rotation speed 8,000 [r/min]
  • Small-sized connector allows horizontal cable connection, which helps to save space in machines (Options supported. (Flange size 90SQ only)).

High-efficiency Spindle Motor SJ-V Series

SJ-V Series
  • A vast range of spindle motors is available, all ready to support diversified machine tool needs.
  • Product line :
    Normal SJ-V series : 0.75 to 55 [kW]
    Wide-range constant output SJ-V series : 5.5 to 18.5 [kW]
    High-speed SJ-V-Z series : 2.2 to 22 [kW]
    Hollow-shaft SJ-VS series : 5.5 to 18.5 [kW]

Low-inertia, High-speed Spindle Motors SJ-VL Series

SJ-VL Series
  • The spindle dedicated to tapping machines requiring faster drilling and tapping.
  • The low-inertia reduces acceleration/deceleration time, resulting in higher productivity.
  • Product line :
    Low-inertia normal SJ-VL series 3.0 to 11 [kW]
    Low-inertia hollow shaft SJ-VLS series 3.7 to 11 [kW]

Tool Spindle Motors HF-KP/HF-SP Series

HF-KP/HF-SP Series
  • Taking advantage of the characteristics of a servo motor such as smallness and high-output, this motor serves as a compact and high-output spindle motor which is capable of high-speed rotation (6,000r/min). This motor contributes to downsizing of spindles, such as the rotary tool spindle.
  • Product line :
    Small capacity HF-KP series 0.4 to 0.9 [kW]
    Medium capacity HF-SP series 2.2 to 4 [kW]

IPM Spindle Motor

IPM Spindle Motor
  • In answer to demands for downsizing and higher efficiency, an IPM motor has been introduced for further energy savings.
  • A reduction in acceleration/deceleration time contributes to shorter cycle times.
