The TM4500 driver is a low cost, unipolar step motor driver designed for 4 phase step motors. The TM4500 is a track mount driver, meaning that it can be quickly mounted on easy to use snaptrack (sold separately). The TM4500 allows the option of using full-step or half-step operation, giving the user the ability to step in either 1.8° or 0.9° increments. The driver can be powered by an AC or DC voltage. For AC operation, the driver may be purchased with a recommended step down transformer. A single transformer may be used to power up several drivers based on power consumption. A major advantage that the TM4500 has over chopper drivers, is that the TM4500 is designed to use bilevel technology. This means that it has replaced the need for high frequency switching techniques, consequently it does not create the EMI, RFI, and motor heating problems that are associated with chopper drivers. This technique makes the TM4500 suitable for applications where low noise requirements are a must. It is especially useful for medical equipment, test instruments, positioning systems, and any other application where noise may be a problem. A transformer or power supply is required, and can be purchased separately.
