Spindle Motors Spindle Motors

High-performance Spindle Motor 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

• 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

• 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

• 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

• 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

• 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

• 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

• 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

• 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.
