World K Series Single-Phase AC Motors & Gear Motors

World K Series Reversible AC Motors

World K Series Reversible AC Motors & Gear Motors

The World K Series AC motors & gear motors offer a wide selection with reliable performance, global agency approvals and conform to the RoHS Directive. These motors come in 1 W (1/750 HP) up to 90 W (1/8 HP) and are available as a round shaft motor only or with a parallel or right angle gearhead.

The outward appearance is the same as that of induction motors, however, these motors are suited for applications where the motor must frequently switch direction.

  • Parallel Shaft, Right-Angle Hollow Shaft and Right-Angle Solid Shaft Worm Gear Motors or Round Shaft Motors
  • Lead Wire or Terminal Box Types
  • Electromagnetic Brake Available
  • Single-Phase 110/115 VAC or Single-Phase 220-230 VAC

Worldwide Standard AC Motors

Safety Standards for Safe, Reliable Operation

All World K Series models have a built-in overheat protection device and conform to major international safety standards. UL/CSA, CE Marking (Low Voltage Directive), models certified under CCC (China Compulsory Certification system) are also available.

Motor Overheat Protection Device

Thermal Protector:
A built-in feature of all motors with a frame size of 2.76 in. (70 mm) or more.
Impedance Protection:
Implemented on all motors with a frame size of 2.36 in. (60 mm) or less.

Global Voltage Specifications

The World K Series supports the power supply voltages used in major countries. Motors meeting the local voltage standard are readily available in major countries in Europe, Asia and North America.

The Motor Bearing Life is Twice as Long as Conventional Type

A motor's life is determined by its bearing. We adopted high-performance bearing grease to lubricate this important component. As a result, the bearings of the World K Series motors last twice as long as conventional bearings.
[Excluding 1 W (1/750 HP) and 3 W (1/250 HP) types.]

Electromagnetic Brake

  • 6 W (1/125 HP)
  • 15 W (1/50 HP)
  • 25 W (1/30 HP)
  • 40 W (1/19 HP)
  • 60 W (1/12 HP)
  • 90 W (1/8 HP)

These motors have a "power off" activated type electromagnetic brake to hold the load in position when the power is cut off.

Ideal for Applications Required Load Holding

This configuration is ideal for vertical applications where the load must be held.

Vertical Application

Brake Pack

Brake Pack

The SB50W provides instantaneous stop, bi-directional operation and electromagnetic brake control functions integrated into one unit. This brake pack can sense when the thermal protector is opened, ensuring the safety of your equipment. For greater convenience, a function has been added to reset alarms using an external signal.


 

 

Flexible Couplings

These products are clamp type couplings used to connect a motor or gearhead shaft to the shaft of the equipment.

 

Mounting Bracket

Mounting Bracket

This is an aluminum die cast mounting bracket for geared motors.

Long, horizontal holes make it easy to make fine adjustments during installation.
