I will explain about the motors of forklifts that are advancing in electrification. #Forklift #ElectricForklift #IndoorForklift

When categorizing the types of power sources for forklifts, they can be broadly divided into two types: engine-powered forklifts that use an engine as the power source and battery-powered forklifts that use a motor as the power source. Among these, gear-integrated motors that are compact yet capable of delivering high torque are gaining attention. Regarding the "motor" of battery-powered forklifts, I would like to explain it as simply and clearly as possible. The control methods for the "motor" of battery-powered forklifts include: - Control methods for DC motors (brushed motors) - Control methods for AC motors (brushless motors) Recently, most battery-powered forklifts have begun to adopt the control method for AC motors (alternating current). Benefits of brushless motors in battery-powered forklift motors: - Since brushes are not used, maintenance of the motor becomes easier. (Achieving maintenance-free operation) - The number of relay switches is reduced, eliminating operational noise during travel. (Reduction of the traditional clicking sound) - The driving performance feeling improves. (Smooth acceleration) - High efficiency of the motor becomes possible.

basic information

The types of "motors" used in battery-powered forklifts are basically drive motors, load handling motors, and power steering motors. Generally, regarding the power steering motor, even the latest battery-powered forklifts still use brushed motors. For the power steering motors in battery-powered forklifts, there are EPS (Electric Power Steering) motors and hydraulic motors, but both are brushed motors, so they need to be checked during maintenance. The maintenance of battery-powered forklifts differs significantly from that of engine-powered forklifts, requiring specialized knowledge and skills related to battery-powered forklifts. It seems that various companies are also developing autonomous electric forklifts.

Applications/Examples of results

Battery-powered devices (such as AGVs), medical pumps, agricultural machinery, conveyors, desktop machine tools, industrial machinery, welfare robots, security robots, industrial electrical equipment, electronic components and semiconductor manufacturing equipment, automotive and transportation equipment, shipbuilding and heavy machinery, testing, analysis, and measurement, manufacturing and research institutions, and others. For those struggling with the miniaturization of robots, we present a new proposal from Coreless Motor Co., Ltd. A reliable robot that demonstrates great power with a small body. Just imagining it is exciting, isn't it? Unfortunately, with conventional motors, the motor and gearhead are separate, making geared motors larger and complicating the miniaturization and lightweight design of the system. The GSH series of coreless motors delivers high torque while maintaining the size of the motor. The key difference comes from utilizing one of the core features of the coreless structure: the hollow structure. By incorporating gears into this hollow part, we have made it possible to save space for the entire system. We want to share the joy of making the impossible possible with you. With this aspiration in our hearts, we support our customers in the miniaturization of motors.
