Permanent Magnet - M type
These instrument stepper motors are high quality permanent magnet types providing a choice of 18 or 7.5 degree step angle. The motors offer excellent performance combined with low pricing. They are ideally suited to instrumentation applications for the small to medium volume user to construct advanced single and multi-axis positioning systems. The motors may be connected cirectly to a dc supply with the same value as the motor. This is often referred to as L/R Drive. For increased high speed performance however it is quiteusual to connect the motor to a higher supply voltage via series resistors since the current rise time in the motor’s coils is proportional to the inductance ( L ) divided by the resistance ( R ) in the drive circuit. Alternatively a more sophisticated drive system can be employed using chopped constant current techniques when the series resistors are not required.
