(Before It's News)

Thepermanent magnet DC motor(PMDC Motor) is a popular drive in industry and commercial applications. While the motor is in operation controllers are used for permanent magnet control or regulation of speed.
Permanent Magnets: A brief explanation
Specifically, how do these DC Motors (Gleichstrommotoren) such as model G30, GR42 and GR53 differ from other common motors used around presently including the shunt wound or series wound motors? It begins to generate voltage of its own, although voltage is put on the coil as it proceeds in the magnetic field. The voltage that is produced gradually cancels out the applied voltage, thereby causing it to be a perpetual motor that is rotating.
The proper phrase that is often used for the generated voltage is “back EMF.” EMF stands for electromotive force. The back EMF (electromotive force) value can be calculated by the magnet’s power in addition to the speed of turning. The more powerful the magnet is, the more the voltage and back EMF (electromotive force) increases. Ironically, a weaker magnet normally makes the motor run at a speed that is higher.
Implementing a load will slow down and reduce the motor speed. In this scenario, the voltage pressure (difference) will grow as the back EMF (electromotive force) decreases. Implementing more voltage will speed up the motor while using less will slow down it. So this can be why permanent magnet controllers are used to control the speed through feedback and voltage use.
Purchasing a permanent magnet controller (Non-regenerative)
All the difference can be made by controlling the speed for your facility’s DC motors.With speed control, the life of the motor will be prolonged and it’ll run smoother than ever. You will have the ability to save on energy and generation prices while also reducing loss of material on account of damage due to high/low rates while stopping and starting the motor.
Check with suppliers such as Powertronic, Shayang Ye andDunkermotoren to source permanent magnet control products to meet your needs. Powertronicoffers one on one help from sales engineers that can assist you to find and locate the right fit for your motor control needs and troubleshoot problems.
