IMS MDrive 23 Plus

The MDrive NEMA 23 high-torque Integrated Motor and Driver is ideal for designers who want the simplicity of a motor with on-board electronics, but without the expense of an indexer on each axis. The low cost MDrive23 allows the system designer to decide the best method of control. The MDrive23's integrated electronics eliminates the need to run the motor cabling through the machine, reducing the potential for problems due to electrical noise.

The MDrive23 uses a NEMA 23 frame size 1.8° high torque motor combined with a microstepping drive, and accepts up to 14 resolution settings from 1/2 to 256 microsteps per step. Setup parameters include Microstep Resolution, Motor Run/ Hold Current, and Motor Direction with respect to the direction input. These settings may be changed on-the-fly or downloaded and stored in non-volatile 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. Operating voltage for the MDrive23 ranges from +12 to +48 or +24 to +75 VDC.

The versatile, compact MDrive23 is available in multiple configurations to fit various system needs. These options include: a single shaft stand-alone device, dual shaft rotary motor with optical encoder or control knob, or a long life Acme screw linear actuator. The rotary MDrive23 is also available in three different stack lengths: 18, 22 & 31. Interface connections are accomplished using either a 12 position keyed and locking pin and receptacle, a 7 position terminal strip, or 12" (30.5cm) flying leads.The MDrive23 is a compact, powerful and inexpensive solution that will reduce system cost, design and assembly time for a large range of stepping motor applications.
