AC Motors

Standard AC Motors & Gear Motors operate by simply connecting a capacitor and supplying power from a commercial power supply. Standard AC Motors & Gear Motors include the basic induction motor and reversible motor. In addition, Oriental Motor offers electromagnetic brake motors, synchronous motors, torque motors and watertight, dust-resistant motors to meet specific application requirements.

  • AC Motor Fundamentals - AC motors are electric motors that rotate by using power from a commercial AC power supply. They are easy to handle and have features that can be configured at a low cost.

Speed Control Motors

For applications where variable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide speed range, low heat and maintenance-free operation. Stepper Motors offer high torque and smooth low speed operation.

  • AGV/AMR Designs: Understanding Brushless Motor Benefits - With an evolving competitive market over the years leading to IOT (Internet of Things) or Industry 4.0., manufacturers are looking for smarter ways to get ahead of their competition. An example of this is the growing trend of Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs), as well as an increase in automated storage and retrieval systems in both warehouses and manufacturing facilities. In this paper, we will provide an introduction to AGV/AMR and discuss why features and characteristics of geared brushless DC motors make them attractive for AGV/AMR’s drivetrain designs.
  • Brushless DC Gear Motors vs Servo Motors vs Inverters - When it comes to speed control, you may think the choice is between an inverter driven three-phase motor or servo motor, but did you know that brushless DC motors specialize in speed control? The brushless DC gear motor is growing in popularity in the world of speed control. However, not everyone is familiar with the power and performance to cost aspects of the brushless DC gear motor. Even in usage situations where it has demonstrated its capabilities, it tends to lag behind the two leading players, the inverter driven three-phase motor and the servo motor. This article introduces the capability of brushless DC gear motors, as well as points to consider when choosing a compact speed control motor.
  • Speed Control Methods of Various Types of Speed Control Motors - A large number of motors are being used for general purposes in our surroundings from house-hold equipment to machine tools in industrial facilities. The electric motor is now a necessary and indispensable source of power in many industries. The function and the performance required for these motors are wide-ranging. When focusing attention on the speed control segment of the motor market, servo and stepper motors control their speed with a pulse train, while the induction motor and the brushless DC gear motor control speed with an external resistor and/or DC voltage.

Stepper Motors

Stepper motors are used to achieve precise positioning via digital control. The motor operates by accurately synchronizing with the pulse signal output from the controller to the driver. Stepper motors, with their ability to produce high torque at low speed while minimizing vibration, are ideal for applications requiring quick positioning over a short distance.

  • Industrial Network Communications - FLEX products In order to meet various requirements, Programmable Logic Controllers (PLCs) and motors/drivers in equipment have been connected in numerous ways, such as pulse train, digital I/O, and fieldbus networks. We have developed products that can be connected to multiple industrial networks. They can be connected to an I/O device and Modbus RTU network. They can also be connected to other field bus networks through a Network Converter (our gateway product). The products can be flexibly connected to a host PLC and it allow customers to select a system depending on their needs. We call this concept FLEX. Since some of the FLEX products have a positioning function, positioning units of host PLCs can be omitted and costs of equipment can be reduced. The FLEX products allow customers to reduce costs and time of developing equipment by using each merit of industrial networks.

Linear Actuators

A linear actuator incorporating a motor and linear-motion mechanism. Drawing on our expertise as a motor manufacturer, Oriental Motor offers a wide range of linear motion products in various shapes and sizes, featuring different motor types, drive methods and power inputs.

  • Method for Calculating Moment Loads on Linear Actuators - An electric linear actuator is a combination product consisting of a linear mechanism and an electric motor, and when pre-assembled offers an easier design, shorter installation time, and high quality. While the actuator is operating, moment loads occur due to not only gravity, but also because of acceleration and deceleration of the load. Because moment loads can damage actuators, confirming that they are within specification is critical. However, calculating moment loads on linear actuators can be complicated and time consuming. This paper describes a method for calculating moment loads in a simple way and makes actuator selection easier.
  • Electric Grippers that Supports Automation One of the latest industrial trend globally is adopting electric grippers for automated production equipment in factories.
