The motor tables in this catalogue show a selection of the motors that we can supply. Your MPS Application Engineer has access to the full range of motors and will be happy to assist you in making the correct selection, considering the operating conditions, appropriate metallurgy, cable and life‐cycle cost.
The unique characteristics of MPS PM motors should be considered when selecting the pump. Both higher and lower speed operation can result in a smaller motor, or a motor that runs cooler. In PCP applications, the most economical solution will use the lowest displacement pump, something which is not feasible with conventional drive heads due to mechanical limitations.
Using the tables
The motor tables follow diameters and applications.
The characteristics of MPS PM motors allow the tables to be ordered by row for output capability and by column for different electrical windings, permitting easy review and selection.
All data is nominal for convenience of tabulation. Electrical nameplate data may vary slightly from that listed.
Our PM motors for ESP applications are specified at 3600 rpm, which is slightly faster than 60Hz induction motors.
Our PM motors for driving PC pumps are specified at 300rpm
and they directly drive the PC pump without requiring a gearbox. They provide greater reliability and a wider operating range, both on torque and speed than gearbox‐connected induction motor driven ESPCP systems. They extend the application range into deviated wells for heavy crude with and without gas. Steady speed operation eliminates rod‐driven system problems from rod and rotor breakages, premature pump wear, tubing wear and substantial rod power losses.
MPS PM motor’s outstanding thermal characteristics can be used to increase production by installing them in places where induction motors cannot go.
The motors share the same design, and in some cases, may be directly swapped between ESP and PCP applications, thereby reducing inventory.

MPS PM motors have straightforward characteristics, each of which shows an advantage over conventional induction motors.
The generic performance curves for MPS PM motors illustrate the following points:
‐ Efficiency is very high over a wide range of power. ‐ Power factor is very high over the full range. ‐ Speed is constant and known ‐ the motor is synchronous and controlled.
These facts are due to the absence of the 40 ‐ 50% magnetising current, which in induction motors generates heat (the rotor and motor oil between the rotor and the stator is even hotter than the winding) and increases power losses in the cable.
The current used by MPS PM motors is entirely productive:
‐ Torque is linear with motor current. ‐ Idle current is negligible. ‐ MPS PM motors stabilise to a safe operating temperature when run indefinitely on the bench. ‐ Power factor is 100% at idle.
Voltage increases with load to maintain constant speed. This is the reason for the decline in power factor with load. It is not the result of magnetising current and does not result in motor losses. Moreover, it has no effect on cable current and so does not create additional cable power losses.
The distinction between MPS PM motors that drive the PMPCP™ and PMESP™ applications is their operating speed. The same high torque permanent magnet motor will operate through a speed range from 50 to 7000 rpm.
MPS PM motors for PCP applications are specified at the conventional rated speed of PCPs, 300rpm. Eliminating rods also eliminates some of the speed restrictions and uncontrolled stick‐slip at the pump that are inherent in rod‐driven PCP systems. For this reason, additional curves for 600 rpm are also provided, permitting higher efficiency and lower system cost with the smaller displacement pumps and sand‐free fluids that support this speed. PCP suppliers are generally more comfortable with speeds of 100 ‐ 300rpm with large pumps. The MPS PMVSD™ drives are designed to work in this range and even right down to 50rpm: a total solution for rod‐less systems.
The generic performance curves for MPS PM motors illustrate the following:
‐ The efficiency has a high peak value which then declines with load. The reason is simple. Because of the low speed, the output power is low. The motor losses remain, so the efficiency must be lower. (In fact, at the same torque, the motor losses are lower than at ESP speeds due to the low friction losses.) Increased output using increased speed will increase the efficiency.
‐ The power factor is very high over the full range. ‐ The speed is constant and known ‐ the motor is synchronous and controlled.
These facts are due to the absence of magnetising current, which in induction motors generates heat (the rotors and the motor oil between the rotor and the stator are even hotter than the winding) and increases power losses in the cable.
The current used by MPS PM motors is entirely productive:
‐ Torque is linear with motor current. The 40 ‐ 50% idle current of induction motors is gone. MPS PM motors at PCP speeds stabilise to a touch‐safe temperature when run indefinitely on the bench. Power factor is 100% at idle.
‐ Voltage increases with load, to maintain constant speed. This is the reason for the decline in power factor with load. It is not the result of magnetising current and does not result in motor losses. Moreover, it has no effect on cable current and so does not create additional cable power losses.
Example. A pump requires 100% torque at 300rpm; motor efficiency is read from the first chart as 56%. An alternative smaller displacement pump may be used, that requires 50% torque at 600rpm. Efficiency is read from the second chart as 84%. Alternatively, a smaller motor can be selected.
