MT40 Series DC Brush Servomotors

MT series is a well-proven range of permanent magnet D.C. brushed servomotors which offers a performance range of 0.5 Nm (4.4 lb-in) to 37 Nm (324 lb-in). Electrical windings are available to suit both low and high voltage drives in order to give optimum current / speed characteristics. All MT motors are fitted with a high precision Tachogenerator as standard. The majority of the range is available with maximum enclosure protection rating up to IP 65.
