Product Description
The MSD – Mega Speed Dynamometer was developed for the testing of very high speed motors such as BLDC, Dental Handpieces, Air Turbines and Surgical Tools. The braking effect is based on Eddy-Current induced on an aluminum disc directly mounted on the DUT (Device Under Test) shaft.
Torque is measured frictionless by a Reaction Torque Sensor mounted under the test bench surface. Due to the thermal effect on the disc, the Mega Speed Dynamometer is not suitable for endurance testing, but can be used to generate a fast curve or perform point to point testing. An infrared sensor monitors the temperature of the disc and stops the test in case of overheating. The disc can be designed and sized according to the motor parameters.
The system is contactless therefore alignment is not critical. Due to this, the system has very low inertia and therefore no residual or drag torque thus having less influence on testing parameters. The speed limitation is based on the Motor Under Test and its ability to drive the disc. Systems reaching speeds over 380 000 rpm have already been manufactured.
MSD-TEST Software is developed in a LabVIEW™ environment. It controls the system and captures the test data. It allows the programing set up of a dedicated test profile.
Every Mega Speed Dynamometer will be adapted around the motor characteristics and performances to match the best possible test results. Specific motor fixtures will be designed to suit each motor form and dimensions. Motor fixtures are available for fixturing handpiece or motor.
Air pressure sensor(s) can be provided as an option. The systems offers 2 analog ±10 VDC outputs as well as 6 analog ±10 VDC inputs (which can be configured for speed, torque, pressure,…) Included calibration weights and arms allow to conduct periodical calibration process supported by a dedicated software routine.
The Mega Speed Dynamometer (MSD System) allows the testing of Dentistry – Handpieces and Motors according to ISO 14457. It enhances Magtrol’s expertise in high-speed applications and ideally complements the WB 23 & WB 27 Dynamometers, enabling motor testing up to 100 000 rpm, with nominal torque of 80 mN·m, 150 mN·m respectively.

Software
Magtrol MSD-TEST is an advanced motor testing software (Windows® based) for data acquisition and system control. Used with the Magtrol Mega Speed Dynamometer, the MSD-TEST determine the performance parameters of a motor / turbine under test. Mechanical properties (torque, speed, power), electrical properties (current, voltage, power) via power measurement system (optional), air pressure (optional) or temperature (optional) can be acquired. The software allow to configure the 2 analog ±10 V outputs as well as the 6 analog ±10 V inputs as needed. Test Set-up can be programmed and recalled any time.The system displays graphs of the tested object’s performances.
Developed in LabVIEW™, MSD-TEST has the flexibility to test a variety of rotating systems in a multitude of configurations. The data generated from this user-friendly program can be stored, displayed and printed in tabular or graphical formats, and is easily imported into a spreadsheet for further analyses. The software integrates a calibration routine, allowing the control and periodical calibration of the MSD Mega Speed Dynamometer.
Magtrol can also make custom modifications to the software to meet additional motor testing requirements.

[post_content] => Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, providing high continuous power ratings (max. 140 kW). WB Series Dynamometers integrate a torque measuring system with accuracy ratings of ± 0.3 % to ± 0.5 % full scale, depending on size and system configuration.
Features
- 12 Models with Maximum Torque from 400 mN·m to 560 N·m (56.6 oz·in to 413 lb·ft)
- Braking Power: from 500 W to 140 kW
- Stable Braking Torque, without Shock
- Low Moment of Inertia
- Low Residual Torque
- Operating Direction CW / CCW
- Braking Torque Measurement Integrated
- High Rotational Speed (≤ 80 000)
- Integrated Optical Speed Sensor
- Special designs available upon request
Operating Principles
The WB Eddy-Current Dynamometers develop their full power at high rotation speeds. The WB Series is particularly intended for motors which rotate at high speeds, up to 80 000 rpm (up to 100 000 rpm with
WB 23 / 27; see specific datasheet). The braking torque depends on the rotation speed.
Optical Speed Sensor
Each WB Series Dynamometer is equipped with an optical speed sensor.
WB 32 is equipped with a 4 PPR (Pulses Per Revolution) encoder, WB 43 and WB 65 HS are equipped with a 30 PPR encoder; WB 65, WB 115 & WB 15 are equipped with a 60 PPR encoder.

[post_content] => Magtrol Coupling Guards are easily removable and designed to mount in front of Magtrol HD Series Dynamometers. They are also available for some WB Series Dynamometers.
Coupling Guards help keep objects from vertical interference and aid in preventing accidental coupling contact during rotation. The guard length required will change according to the coupling size used with the dynamometer.
Magtrol Coupling Guards are not explosion proof and are not intended as protection against catastrophic coupling failure.
