PMSM motor range: 24 V to 565 V
Innotec Power is a permanent magnet motor manufacturer. We design and build PMSM motors at our own plant in Faridabad, India, and support them from our US office in Charlotte, North Carolina. More than 350 models are published with full ratings, so a motor can be sized against its duty cycle rather than a single headline number.
| DC bus | Models | Continuous power | Continuous torque | Rated speed | Rotor |
|---|---|---|---|---|---|
| 24 V | 73 | 0.1 – 13 kW | 1 – 152 Nm | 45 – 5,700 rpm | SPM and IPM |
| 48 V | 147 | 0.2 – 27.3 kW | 0.9 – 543 Nm | 35 – 6,400 rpm | SPM and IPM |
| 72 V | 63 | 1.1 – 37 kW | 2.8 – 217 Nm | 650 – 5,800 rpm | SPM and IPM |
| 96 V | 37 | 0.9 – 31.3 kW | 3.6 – 373 Nm | 180 – 4,800 rpm | SPM and IPM |
| 400 / 565 V | 31 | 1 – 120 kW | 19 – 912 Nm | 60 – 3,000 rpm | SPM |
Every model is published at three duty points — continuous, 60 minutes and 15 minutes — so an intermittent-duty application can often use a smaller frame than its peak load would suggest. Popular ratings have their own comparison pages: 48V 10kW, 72V 10kW, and IPM versus surface-magnet rotors.

Permanent magnet (PM) motors are electric motors that use permanent magnets to generate the magnetic field instead of external excitation. This design offers high efficiency, compact size, and robust torque — making them ideal for modern applications like pump drives, HVAC systems, traction, and more.
Our PM motors leverage best-in-class materials and engineering standards to deliver consistent performance across duty cycles, whether in heavy-duty industrial settings or sensitive applications like telecom backup or marine systems.
PMSM motors: common questions
What is a PMSM motor?
A permanent magnet synchronous motor is an AC motor whose rotor carries permanent magnets instead of windings or a squirrel cage. The stator is fed with sinusoidal three-phase current and the rotor turns in exact synchronism with the rotating stator field, so there is no slip. Because the rotor field costs no excitation current, a PMSM runs cooler and more efficiently than an induction motor in the same frame, and it holds that efficiency across a wide speed range.
Is a PMSM better than a BLDC motor?
They are largely the same machine driven two different ways. A BLDC motor has a trapezoidal back-EMF and is commutated in six steps; a PMSM has a sinusoidal back-EMF and is driven with field-oriented control. The PMSM gives smoother torque, lower acoustic noise and better part-load efficiency, while the BLDC drive is simpler and cheaper. For pumps, traction and anything a person sits on or stands near, sinusoidal control is usually worth the extra drive cost.
What are the disadvantages of a PMSM motor?
Three matter in practice. Rare-earth magnets make the motor more expensive per kW than an induction machine. The magnets are temperature sensitive, so sustained over-temperature can partially demagnetise the rotor, which is why duty ratings rather than peak figures should drive selection. And a PMSM always needs an electronic drive with rotor position information; it cannot be started direct on line.
How is a PMSM motor controlled?
With a field-oriented, or vector, controller. The drive measures phase currents and rotor position, resolves the current into a torque-producing component and a flux-producing component, and regulates each independently. Position comes from a resolver, an encoder or Hall sensors, or is estimated in sensorless schemes above a minimum speed. Above base speed the drive can inject negative flux current to weaken the field and extend the speed range, which is where an interior-magnet rotor has the advantage over a surface-magnet one.
Does Innotec Power supply custom PMSM motors?
Yes. Winding, shaft, flange, connector and feedback options are changed to order, and new frames are developed against a customer duty cycle. Send the torque-speed profile, the DC bus voltage and the duty pattern and we will size against it. See custom PMSM motors.
