Compatible Panasonic CM / NPM X / Y / Z-axis motors: head motors, axis motors and angle motors

Supply type: for the same part number we may offer new parts (not through the brand’s authorized distributor in Taiwan), compatible parts or used parts removed from machines, depending on stock. Please tell us which you need.

Panasonic placement machine motors (also called Panasonic CM / NPM axis motors or placement machine servo motors) are the servo motors that drive each axis — X, Y, Z and angle — on Panasonic CM, NPM and other placement machines, using encoder feedback to control position. This page covers head motors and X / Y-axis motors from CM101 to NPM, plus MSM and HC-MFS series AC servo motor models.

Every axis on a Panasonic placement machine is driven precisely by a servo motor. Motor specs differ by axis (X / Y / Z / angle) and machine model, with power ratings from 3 W to 50 W. Typical signs of a failing motor are reduced positioning accuracy, machine alarms (servo drive error) or abnormal noise. Once you have confirmed which axis is at fault, you can ask by part number and shorten the downtime wait.

Three things to match: ① machine model (CM402 / CM602 / NPM) ② axis (X / Y / Z / H / angle) ③ power (3 W / 4 W / 15 W / 20 W / 25 W / 50 W). With all three confirmed, the part number can be matched precisely.

Z-axis head motors

X / Y-axis motors

BM / MSR and other machines

Check the model: motor part numbers must match the machine model, axis and power. Send us the old part number or the machine serial number and we will help match it to avoid ordering the wrong motor.

AC servo motor models (grouped by series)

The tables above list head and axis motors by machine, axis and power. Below are other AC servo motor models commonly found on Panasonic placement machines, grouped by series. If you cannot find the model you have, send the old part number or machine serial number and we will help match it.

AC servo motors I: N606HCSFS102 / KXF0DX1BA00 / N510042739AA

AC servo motors are the core drive for high-precision X / Y positioning. They have many parameters, so please give the full part number and machine model before ordering, and our sales team will confirm. After replacement, home position setting and axis gain tuning must be redone.

AC servo motors II: MSM082AJA / MSM082A4A / MSM042AJB

Servo parameters must be reset after replacement.

AC servo motors III: MSM011P1A / MSM5AZPJA / MFA010LA2NSK

Low-power servo motors are mostly used on Z axes, rotary axes and other short-stroke, high-precision mechanisms. There are many models, so please give the full model and machine details before ordering.

AC servo motors IV: HC-MFS73 / HC-MFS43 (Mitsubishi Electric)

The S23 and S24 encoder versions are not interchangeable. Before ordering, confirm the encoder type your machine controller currently uses.

P50BA2002BXS3C / N510046420AA / MSM022AJB2

The three differ in power and mounting spec. Motor specs involve voltage, power and mounting dimensions, so please give the machine model and the part number in use before ordering.

CM101 / CM202 Y-axis motor and CM301 Z-axis motor

These are common parts for repairing older machines. Motor replacement involves mechanical installation and parameter setting, so it should be done by a technician with repair experience; after replacement, check each axis’s home position and stroke settings.

FAQ

What is a servo motor, and why do placement machines use them? A servo motor is a closed-loop motor: an encoder sits beside the motor, and the controller compares the measured position with the target position and uses the difference to correct the motor, stopping once it is in place. On Panasonic placement machines, the X, Y, Z and angle axes are all driven by servo motors. Source: Wikipedia, “Servomotor”.

What is the difference between a servo motor and a stepper motor? Position feedback. A servo motor has an encoder, and the drive continuously compares commanded and actual position and corrects it — closed loop. A typical stepper motor has no position sensor and turns step by step as commanded — open loop — without checking where it actually stopped, so it can lose steps under heavy load or resonance. Sources: A3 (Association for Advancing Automation), “Servo vs Stepper Motors”; Wikipedia, “Stepper motor”; Wikipedia, “Servomotor”.

What happens when a Panasonic placement machine motor fails? Typical signs are reduced positioning accuracy, a servo drive error alarm, or abnormal motor noise. Confirm which axis is affected first, then ask by part number to shorten the downtime wait.

How do I confirm which motor to replace? Match three things: machine model (CM402, CM602, NPM, etc.), axis (X, Y, Z, H, angle) and power (3 W, 4 W, 15 W, 20 W, 25 W, 50 W). With these confirmed, the part number can be matched. Send us the old part number or machine serial number and we will help match it to avoid a wrong order.

What power ratings do the Z-axis head, X / Y-axis and angle motors have? The Z-axis head motors on this page are rated 3 W, 4 W, 15 W, 20 W and 25 W: CM402 has 15 W and 20 W, CM402 / CM602 share 3 W; NPM has 3 W, 4 W, 15 W and 25 W; the CM 3-head machine has 25 W. The angle motor is 50 W (CM402 / CM602). The X / Y-axis motor table lists machine models and part numbers (CM101, CM212, CM402).

What are Mitsubishi HC-MFS43 and HC-MFS73 servo motors? HC-MFS is a Mitsubishi Electric MELSERVO AC servo motor series, classed in Mitsubishi’s manual as “ultra-low inertia, small capacity”. In the model number, 43 means 400 W and 73 means 750 W, with a rated speed of 3000 r/min. The X / Y-axis motor table on this page lists HC-MFS43 part numbers, and the AC servo motor tables list HC-MFS73-S24, HC-MFS73-S23 and HC-MFS43-S24. The S23 and S24 encoder versions are not interchangeable; confirm the encoder type your controller uses before ordering.

Which supply types are available for the same part number? For the same part number we may offer new parts (not through the brand’s authorized distributor in Taiwan), compatible parts or used parts removed from machines, depending on stock. Please give the part number and tell us which you need.
