Introduction to the MDrive34Plus Microstepping

The MDrive34Plus Microstepping high torque inte- grated motor and driver is ideal for designers who want the simplicity of a motor with on-board electronics. The integrated electronics of the MDrive34Plus eliminate the need to run motor cabling through the machine, reducing the potential for problems due to electrical noise.

The unsurpassed smoothness and performance delivered by the MDrive34Plus Microstepping are achieved through IMS's advanced 2nd generation current control. By apply- ing innovative techniques to control current flow through the motor, resonance is significantly dampened over the entire speed range and audible noise is reduced.

The MDrive34Plus accepts a broad input voltage range from +12 to +75 VDC, delivering enhanced performance and speed. Oversized input capacitors are used to mini- mize power line surges, reducing problems that can occur with long runs and multiple drive systems. An extended operating range of –40° to +75°C (heat sink), –40° to

+90°C (Motor) provides long life, trouble free service in demanding environments.

The MDrive34Plus uses a NEMA 34 frame size high torque brushless motor combined with a microstepping driver, and accepts up to 20 resolution settings from full to 256 microsteps per full step, including: degrees, metric and arc minutes. These settings may be changed on-the-fly or downloaded and stored in nonvolatile memory with the use of a simple GUI which is provided. This eliminates the need for external switches or resistors. Parameters are changed via an SPI port.

The versatile MDrive34Plus Microstepping is available in multiple configurations to fit various system needs. Ro- tary motor versions come in three lengths and may include an internal optical encoder, control knob or planetary gearbox. Interface connections are accomplished with either a pluggable locking wire crimp or 12.0" (30.5 cm) flying leads.

The MDrive34Plus is a compact, powerful and inexpensive solution that will reduce system cost, design and assem- bly time for a large range of brushless motor applications.

Configuration Interface

The IMS Motor Interface software is an easy to install and use GUI for configuring the MDrive34Plus from a computer's USB port. GUI access is via the IMS SPI Motor Interface included on the CD shipped with the prod- uct, or from www.imshome.com. Optional cables are available for ease of connecting and configuring the MDrive.
