Product Description

Magtrol’s Customized Motor Test Systems (CMTS) are PC-based, turnkey systems custom designed and built to meet your specific motor testing requirements. By integrating Magtrol’s motor test equipment with power supplies, adaptable fixtures, custom tables/cabinets, printers, etc., Magtrol’s engineering team can design and build a system that precisely suits the customer’s needs.

A Magtrol CMTS may contain any of the following:

  • One or more dynamometers
  • Programmable dynamometer controller
  • Power analyzer
  • M-TEST Software (or custom variations)
  • Motor power supply (AC and/or DC) for the motor under test (MUT)
  • Rack mounted computer, monitor and keyboard drawer
  • Dynamometer table or custom structure
  • Motor fixturing for test motors
  • Temperature measurement hardware
  • On-site commissioning & technical training

Selection

There are four key items that need to be addressed in selecting the proper motor test system:

  • What type of motors are to be tested?
  • What is the maximum Torque, Speed and Power of the motors?
  • What motor test parameters need to be measured?
  • What are the available utilities to power the system where it is installed?

Magtrol Dynamometers can be used to test virtually all types of electric, hydraulic and pneumatic motors, as well as internal combustion engines.

Using a Magtrol DSP7000 Dynamometer Controller or the basic Model 6200 manual controller, the user can view speed, torque, and mechanical power (in horsepower or watts) in real time.   When using our MTEST software with a DSP7000, complex test profiles can be created and the data collected and graphed.

Magtrol also offers systems based on AC Motors with Vector drives or Servo Motor based systems.  These systems can provide driving as well as brake functions.  Optional regenerative modules improve efficiency by returning excess electrical power to the power grid.

Magtrol offers Single and Three-Phase Power Analyzers. The Power Analyzer option allows measurement Volts, Amps, Watts and Power Factor.

                    [post_content] => The Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Like Hysteresis Brakes, Powder Brakes provide full torque at zero speed. Like the Eddy-Current Brake Dynamometers, the PB series are water-cooled, allowing for power ratings up to 48 kW. The PB Dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale (± 2% for PB 2.7), depending on size and system configuration. Additional mounting possibilities include speed pickup and OEM version IS.

Features

  • 12 Models with Maximum Torque from 600 mN·m to 1 200 N·m (84 oz·in to 885 lb·ft)
  • Braking Power: 150 W to 48 kW
  • Stable Braking Torque
  • Low Moment of Inertia
  • Operation in Either Rotational Direction
  • Braking Torque Measurement Integrated
  • Integrated Optical Speed Sensor
  • Special designs available upon request

Operating Principles

The PB Series - Powder Dynamometers contain, as their name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction between rotor and stator. The Powder Dynamometers (PB) produce their rated torque at zero speed. The element to be tested can be loaded at standstill to determine the starting torque. Optical Speed Sensor Each PB Series Dynamometer has an optical speed sensor delivered as standard. PB 2.7 & PB 43 has an optical speed sensor with a 30-bits pulse wheel; PB 65, PB 115 & PB 15 has an optical speed sensor with a 60-bits pulse wheel. For higher speed resolution in low speed applications, Magtrol offers a 600-bit or 6000-bit speed pickup (encoder) as an option.

To better integrate dynamometers into systems, Magtrol offers both long and short base plates.  The shorter base plate facilitates easier motor mounting when used with T-slot tables and Magtrol Adjustable Motor Fixtures, where as the long base plates are better suited for table top testing.

Features

  • 16 Standard Models with Maximum Torque from 2.5 oz·in to 500 lb·in (18 mN·m to 56.5 N·m)
  • Hysteresis Braking System: Provides precise torque loading independent of shaft speed
  • Motor Testing from No Load to Locked Rotor
  • Accuracy: ±0.25% (Full Scale)
  • Air Flow Sensor: For protection against overheating and operator error
  • Standard Torque Units: English, Metric and SI
  • Base Plate: Available in long or short versions
  • Custom Dynamometers: for special torque and speed requirements
  • Easy Calibration

The Hysteresis Braking System

All Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis Braking System which provides frictionless torque loading independent of shaft speed. The Hysteresis Brake provides torque by the use of two basic components - a reticulated pole structure and a specialty steel rotor/shaft assembly - fitted together but not in physical contact. Until the pole structure is energized, the drag cup can spin freely on its shaft bearings. When a magnetizing force from the field coil is applied to the pole structure, the air gap becomes a flux field and the rotor is magnetically restrained, providing a braking action between the pole structure and rotor.

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. The water cooling in the WB provides high continuous power ratings (max. 140 kW). The WB dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale (± 2% for WB 2.7), depending on size and system configuration. Additional options include: high-speed version, speed pickup, mechanical rotor blocking device, OEM version IS and vertical mounting.

Features

  • 13 Models with Maximum Torque from 300 mN·m to 560 N·m (42 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
  • 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 65 000 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 has an optical speed sensor delivered as standard. WB 2.7 & WB 43 has an optical speed sensor with a 30-bits pulse wheel; WB 65, WB 115 & WB 15 has an optical speed sensor with a 60-bits pulse wheel.
