The main application of a small electric motor lies in a wide range of products due to its compact size and high power to weight ratio. These small electric motors can help you conserve energy as well as create comfortably compact and convenient mechanical systems. The motors are often found in several home appliances like mixer, blender, garage doors, hair dryers, etc.

These motors are mainly used in automating one or more processes in a factory that deals with the mass production of products. The credit to the recent popularity of small motors goes to the ecological as well as economic benefits that they give to major industries of the 21st Century. Sugawara is one such company that has pioneered in making torque dynamometers at a large scale. The company is one of the leading electric motor testing equipment suppliers.

The main feature of the dynamometers produced by Sugawara includes a noiseless as well as ripple-free mechanical operation. The main belief of the company lies in the fact that the motor characteristics must be measured with accurate load control systems that are suited to the characteristics of the target motors. This belief has successfully secured the support of several clients of the company.

Following are the various products offered by Sugawara Laboratories, a well reputed Electric Motor Testing Equipment Supplier

Motor Torque Testing Systems

The motor torque testing systems produced by Sugawara laboratories are known in the industry as some of the most reliable equipment for measurement and testing purposes. The systems are capable of accurately and precisely grasping load characteristics, cogging torque characteristics as well as torque ripple characteristics for effective electric motor performance evaluation. With Sugawara laboratories, you can easily find an entire family of motor torque meter systems that work in conjunction with each other to measure all these necessary characteristics in one go. You can also process and evaluate the data out of these tests to come up with logical conclusions for the testing phase. The torque sensors are not ideal in case of measuring the different load characteristics, torque ripple characteristics and cogging torque characteristics. This is why you need three different highly precise devices from Sugawara laboratories to measure all characteristics effectively.

Sugawara Laboratories function on optimal measurement principles to develop the measurement elements for high precision. They manufacture all the critical components for measurement including brakes, sensors, control methods as well as jigs. Apart from this the company also serves as one of the best electric motor testing equipment suppliers at a global scale.

Sugawara Laboratories offers 14 models of Torque Dynamometer with torque rating ranging from 5 mN.m to 100 nN.m and with RPM ranging from 100-40,000rpm. Along with the above-mentionedmodels, Sugawara Laboratories offers a line of Cogging Torque and Torque Ripple Meters with ratings ranging from 0.5mN.m to 200 N.m. Integrated with a controller and a personal computer these models measures the parameters accurately and with consistency.

Motor Torque Testing Systems offered by Sugawara Laboratories are specially designed for small and mid-sized motors.The motor torque testing systems work best with the products from a reliable electric motor testing equipment supplier.


Torque Tester for Stepper Motors

This model of Motor Torque Tester offered by Sugawara Laboratories measures pull-in and pull-out torque of stepper motors. The company also manufactures supersensitive sensors that enable the accurate as well as reliable measurement of micro-stepper motor torque of less than 0.1mN.m. You can also use the device for extremely small stepper motors having a testing torque less than 0.002mN.m.

This model is highly efficient in measuring the torque of stepper motors under various operating conditions. The credit to this accuracy goes to the use of Prony (winding) braking method that allows high-performance testing of these stepper motors. This tester is coupled with a comprehensive software that gives a precision of up to 20N while measuring pull-in and pull-out torque.

Ultra High-Speed Motor Torque Testers

High-speed motors, even ones with low torque and small structures, can produce high output power. They have generated high expectations for efficient energy conversion and energy saving. The exceptional EMA-100 and EMM-100M motor torque meters have the capacity to measure the load characteristics of high-speed motors precisely. Sugawara Laboratories use highly functional and accurate small-diameter cylindrical brake rotor to effectively tackle the challenge of torque measurement. You can use these rotors in conjunction with the measuring equipment on super high-speed motors running at over 300,000 revolutions per minutes without any load. A newly developed proprietary coupling solved the problem of shaft coupling of high-speed motors.

Effective Hysteresis Brake Units for Motor Testing

The Sugawara Laboratories’ high-performance brake units are suitable for use in motor dynamometers as well as dedicated measuring jigs. The HB series of the hysteresis brake unit applies an equal braking force depending upon the electric current supplied. This allows you to contain the rotation speed according to your needs without any barriers. These brake units are extremely compact, high-performance and easy-to-use for load applying device. You can use the measurement devices for calculating the motor speed and torque characteristics efficiently. Combining this testing unit with other products from a reliable electric motor testing unit supplier will give you the confidence to achieve consistent results with each test.
